    Life cycle assessment of bread produced on different scales1999In: The International Journal of Life Cycle Assessment, ISSN 0948-3349, E-ISSN 1614-7502, Vol. 4, no 1, p. 25-40Article in journal (Refereed)
    Abstract [en]

    A case study of white bread has been carried out with the purpose of comparing different scales of production and their potential environmental effects. The scales compared are: home baking, a local bakery and two industrial bakeries with distribution areas of different sizes. Data from the three bakeries and their suppliers have been collected. The systems investigated include agricultural production, milling, baking, packaging, transportation, consumption and waste management. Energy use and emissions have been quantified and the potential contributions to global warming, acidification, eutrophication and photo-oxidant formation have been assessed. The large industrial bakery uses more primary energy and contributes more to global warming, acidification and eutrophication than the other three systems. The home baking system shows a relatively high energy requirement; otherwise, the differences between home baking, the local bakery and the small industrial bakery are too small to be significant.

    Screening life cycle assessment (LCA) of tomato ketchup: A case study1998In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 6, no 42067, p. 277-288Article in journal (Refereed)
    Abstract [en]

    A screening life cycle assessment (LCA) of tomato ketchup has been carried out. The purpose was to identify 'hot-spots', that is parts of the life-cycle that are important to the total environmental impact. The system investigated includes agricultural production, industrial refining, packaging, transportation, consumption and waste management. Energy use and emissions were quantified and some of the potential environmental effects assessed. Packaging and food processing were found to be hot-spots for many, but not all, of the impact categories investigated. For primary energy use, the storage time in a refrigerator (household phase) was found to be a critical parameter. © 1998 Elsevier Science Ltd. All rights reserved.

    Density measurements of single granules using the atomic force microscope2005In: Journal of The American Ceramic Society, ISSN 0002-7820, E-ISSN 1551-2916, Vol. 88, p. 2322-2324Article in journal (Refereed)
    Abstract [en]

    The density of single spray-dried granules has been determined with a new method based on the atomic force microscopy (AFM). Spherical granules with a well-defined diameter are attached to the AFM cantilever, which acts as a beam type spring, and the mass of a granule is estimated from the shift in the resonant frequency. The error of the measurements associated with the method was estimated to vary between 1-5% depending on the size and shape of the granule. Density measurements of spray-dried WC-Co granules are presented and the effect of a polymeric binder and dispersant on the consolidation during drying is discussed

    DLVO interactions of tungsten oxide and cobalt oxide surfaces measured with the colloidal probe technique2002In: Journal of Colloid and Interface Science, ISSN 0021-9797, E-ISSN 1095-7103, Vol. 246, p. 309-315Article in journal (Refereed)
    Abstract [en]

    We have investigated the DLVO surface forces of oxidised tungsten and cobalt surfaces using the atomic force microscope (AFM) colloidal probe technique. It was shown by X-ray Photoelectron Spectroscopy (XPS), and electrokinetic measurements that this model system is representative for industrial WC and Co powders used in the production of hard metals. We found that the attractive van der Waals forces are well described by Hamaker constants, calculated from optical data for WO3 and CoOOH. The repulsive electrostatic double layer forces between WO3 surfaces increase with increasing pH due to an increasingly negative surface potential. This surface potential decreases with increasing ionic strength at pH 7.5. The electrostatic interaction between WO3 and CoOOH is attractive at pH 10, suggesting a positively charged CoOOH surface.

    Effect of cobalt ion and polyethyleneimine adsorption on the surface forces between tungsten oxide and cobalt oxide in aqueous media2002In: Journal of The American Ceramic Society, ISSN 0002-7820, E-ISSN 1551-2916, Vol. 85, p. 2404-2408Article in journal (Refereed)
    Abstract [en]

    We used the colloidal probe technique with the atomic force microscope (AFM), to study the interactions between a tungsten oxide sphere, WO3, and flat oxidized tungsten and cobalt surfaces in aqueous electrolytes. We have investigated the effects of adsorption of cobalt ions to tungsten oxide surfaces and adsorption of polyethyleneimine (PEI). Low concentrations of cobalt ions to a WO3system resulted in extended hydration forces and lower absolute value of the surface potential. It was shown that PEI adsorbs to the WO3 surfaces and induces an electrosteric repulsion in both the symmetric (WO3-WO3) and asymmetric (WO3-CoOOH) system. The possible complexation of cobalt ions with PEI does not significantly influence the thickness of the adsorbed layer

    Friction and adhesion of single spray-dried granules containing a hygroscopic polymeric binder2005In: Powder Technology, ISSN 0032-5910, E-ISSN 1873-328X, Vol. 155, p. 101-107Article in journal (Refereed)
    Abstract [en]

    The atomic force microscope has been used to study the friction and adhesion of single spray dried granules containing a mixture of fine tungsten carbide and cobalt powders and various amounts of a polymeric binder, polyethylene glycol (PEG). The adhesion or the pull-off force and the friction force between two single granules (representing intergranular friction) and between a granule and a hard metal substrate (representing die-wall friction) have been determined as a function of relative humidity. We found that the granule-wall friction increases with binder content and relative humidity. The small friction force at the lowest addition of PEG was related to a small contact area due to the high surface roughness of the granules. The substantial increase in the friction coefficient at PEG-addition>1wt% was related to the plasticity of the binder-rich granule surface where an increase in binder content or relative humidity increases the deformability. The granule-granule friction and adhesion is independent of the relative humidity and substantially lower than the granule-wall friction at all PEG contents, which has important implications for the handling of granular matter

    Oxidation and dissolution of tungsten carbide powder in water2000In: Int J Refract Met Hard Mater, ISSN 0263-4368, Vol. 18, p. 35-43Article in journal (Refereed)
    Abstract [en]

    The oxidation and dissolution of tungsten carbide powder dispersed in water was investigated using XPS and leaching studies. We found that the WO3 surface layer on the oxidised tungsten carbide powder dissolves readily at pH>3 with the tungsten concentration increasing linearly with time. Adding cobalt powder to the tungsten carbide suspension resulted in a significant reduction of the dissolution rate at pH<10, when the concentration of dissolved Co is high in the solution phase. Electrokinetic studies indicate that the reduced dissolution rate may be related to the formation of surface complexes; experiments showed that Co species in solution adsorb on the oxidised tungsten carbide powder. The experimental data were discussed in relation to theoretical modelling of the WO3 solution chemistry and the Co2+ adsorption at oxide/water interfaces

    Putsning av möbelkomponenter med hjälp av industrirobot1990Report (Other academic)
    Abstract [sv]

    Gjorda försök visar att industrirobotar kan utnyttjas för finputsning av träkomponenter. Det är dock nödvändigt att detaljerna tillverkas så att form och mått kan förutsägas inom givna toleranser. I många fall kan detta krav uppfyllas genom CNC-bearbetning. Mindre detaljer kan med fördel hållas av roboten, större laminerade detaljer bör spännas upp i fixturer. Rekommendationer om hur man bör gå till väga finns i rapporten.

    Continuous preventive bridge maintenance in Sweden - Field experiment on the effect of washing on concrete bridges2019In: Proceedings of the fib Symposium 2019: Concrete - Innovations in Materials, Design and Structures, International Federation for Structural Concrete , 2019, p. 1135-1141Conference paper (Refereed)
    Abstract [en]

    Bridges are an important part of the infrastructure. For the bridges to have the longest possible service life with minimum repairs, the maintenance is of great importance. One type of bridge maintenance that is rarely researched is the continuous preventive maintenance. The continuous preventive maintenance consists of removal of vegetation, cleaning of bridge joints and drainage systems as well as high-pressure washing of the structure. The effects of washing is heavily discussed but not properly researched. A study on the effectiveness of washing concrete is therefore being conducted. A field experiment has been initiated where concrete specimens are installed on an edge beam of a road bridge. The specimens are of two recipes where one represents an old bridge with rather high water-cement ratio and the other one represents a new bridge with a low water-cement ratio. 50% of the specimens are washed annually, while the others are not. Each year samples are collected and tested for a chloride profile. The results for the first year of exposure have been determined. They are promising but are still only very preliminary. The effect of washing, if any, will be visible after a longer exposure.

    Försök med montering av trämöbler med industrirobot visar att de detaljer som skall monteras måste vara "formsäkra" inom givna måttoleranser för att monteringen skall bli säker. Gripning av detaljerna med vakuum fungerar mycket bra. De många momenten leder dock till många tidskrävande verktygsväxlingar.

    Packages for liquids - Internal Pressure Test2008Report (Refereed)
    Abstract [en]

    The basic requirements for transport of dangerous gods are that a packaging shall be able to withstand certain mechanical and chemical stresses, as stated in SRVFS 2006:7. The requirements shall guarantee a reasonable level of protection for both humans and environment and is intended to create a system taking into account different types of substances and packaging. Principles for classification, packing requirements, testing procedures shall be simple and clear and guarantee that a minimum level of safety can be achieved without advanced technical equipment and expertise. No requirements concerning test temperatures are given in the regulations but in the standard SS-EN-ISO 16104:2003 “Packaging – Transport packaging for dangerous goods – Test Methods” the internal hydraulic pressure test, for plastics drums, jerricans and composite packaging, shall be performed at a temperature of +12 °C, otherwise the internal test pressure shall be adjusted with a pressurization factor corresponding to the temperatures used in the test. At temperatures below +12 +/- 2 °C the test pressure is increased and if the temperature is higher the pressure is lowered. Correction factors exist from +2 °C to +20 °C, and for all temperatures above +20 °C the correction factor is the same as for +20 °C. Neither ADR, IMDG-code, ICAO-TI or the UN-recommendations recommend any test temperature. The aim with this project was to perform internal pressure test at different water temperatures. Three jerricans of each type were tested at the following temperatures: +3, +20, +40 and +55 °C. As can be seen in the test results the burst pressure decreases substantially with rising temperature. For jerrican A the burst pressure is reduced from 234 kPa at +3 °C to 175 kPa at +20 °C, 151 kPa at 40 °C and 114 kPa at +55 °C. At +55 °C the burst pressure is reduced to less than half what it was at +3 °C. Jerrican B is also reduced from 545 kPA at +3 °C to 226 kPa at +55 °C while jerrican C is only reduced from 185 kPa to 136 kPa in the same temperature interval. The gradient of the correction factor in table 3 in EN ISO 16104:2003 correspond very well with gradient of the tested jerricans in the temperature span between +2 °C and +20 °C. All jerricans were made of PE. The pressure/temperature curves show a linear gradient but indicates that the gradient can differ between different materials. Jerrican A and B are produced by the same manufacturer in the same material and show corresponding behaviour, also corresponding to the correction factors in the standard. Jerrican C is produced by another manufacturer and does not show such significant reduction of burst pressure at higher temperatures.

    Fönsterlyft2013Report (Refereed)
    Abstract [sv]

    Detta projekt syftar till vidareutveckling av en uppfinning som har potential att väsentligen förenkla och effektivisera ett arbetsmoment, att lyfta av och på utåtgående sidohängda fönster, som är ett välkänt arbetsmiljöproblem. Resultatet från undersökningen visar att verktyget har utvecklingsmöjligheter och att radikalt minskar de ergonomiska problemen och att användningen kan ge goda möjligheter att effektivisera arbetet. Verktyget måste betraktas som ett lyftredskap och omfattas av därför av ett regelverk som innebär att vissa kriterier måste uppfyllas. Undersökningar i detta projekt visar att verktyget uppfyller de formella krav som ställs på det. Undersökningen visar också att det fungerar på avsett sätt dvs för att lyfta ur och sätta tillbaka utåtgående sidohängda fönster. Verktyget har provats av branschfolk som varit positiva till lösningen men bedömt den som svår att använda beroende på att den består av för många delar och att det är en stor förändring jämför med dagens arbetssätt med två man i arbetslaget. Med hänsyn tagen till de synpunkter som kommit från branschfolk i detta projekt är ett naturligt nästa steg att förenkla och anpassa verktyget till ett tvåmansverktyg. Verktyget blir då mer lättanvänt för ett arbetslag på två personer. Tillverkningskostnaden blir dessutom lägre för det anpassade verktyget. Om den förenklade lösningen får ett genomslag på marknaden innebär detta att företaget kommer igång med försäljning och produktion. I ett senare skede kan företaget vidareutveckla och marknadsintroducera det enmans-verktyg som var ursprunget till detta projekt och som fortfarande bedöms vara den allra effektivaste lösningen för arbetsmomentet att lyfta av och på fönster.

    Från living labs till transition labs - En forskningsöversikt och kartläggning av innovationsmiljöer för hållbara städer2018Report (Other academic)
    Abstract [sv]

    Samhällen ställs i allt större grad inför komplexa utmaningar som blir allt svårare att hanteramed befintliga resurser och arbetssätt. För att kunna skapa förutsättningar för ett välmående,ekologiskt och socialt hållbart samhälle, nu och i framtiden, behöver en omfattande kursändringske. Behovet av sociala, organisatoriska och tekniska innovationer, som på olika sättbidrar till att ersätta ohållbara energi- och transportsystem samt föråldrade sätt att producerasamhällstjänster och kunskap på, är stort.Den samhällsvetenskapliga forskningen lyfter fram vikten av bred samverkan mellan sektorsochmyndighetsgränser för att kunna ta sig an komplexa hållbarhetsutmaningar. Dagensstuprörstänkande försvårar gemensam kunskapsproduktion och problemlösning. Däremotfinns det tecken på att den traditionella, hierarkiska och centralistiska samhällsstyrningenhåller på att omformas till att bli mer nätverksbaserad, horisontell och samarbetsbaserad.Denna styrningsform - som i den engelska litteraturen kallas för governance - bygger i högre gradpå nätverkande och flernivåsamverkan mellan näringsliv, offentlig sektor och civilsamhället.När det gäller hållbar utveckling och innovation anses städerna spela en allt viktigare roll. Delsär städer kraftfulla påverkansnoder som främjar spridningen av radikala innovationer; dels bidrarstädernas unika synergier och tillgång till infrastruktur, kapital och kompetenser till ökadinnovationsförmåga. Hur skall städerna organisera sig för att kunna öka samverkan och främja ettexperimentellt förhållningssätt för att kunna ta sig an komplexa utmaningar? Hur skallstäderna organisera sig för att dra nytta av den ökade innovationsförmågan givet desamhällsutmaningar vi står inför?I Sverige och internationellt har nya typer av organisationsformer och arenor börjar växa framsom ett svar på ovan tecknade utmaningar: urban living labs, urban transition labs, social labs, policy labs,innovationsplattform för att ta några exempel. Alla dessa miljöer har som syfte att främja flernivåsamverkan,innovation och problemlösning. I Sverige främjas denna utveckling främst tackvare innovationsmyndigeten Vinnova som på olika sätt stödjer dessa framväxande försök atthitta nya typer av organisationsformer. I Europa sker stora satsningar på liknande miljöergenom Horizon 2020 och JPI Urban Europe. Syftet med den här rapporten är att ge en bild avhur dessa nya innovationsmiljöer växer fram som styrverktyg för att driva hållbar stadsutveckling.I anslutning till rapporten har även gjorts en kartläggning och klassificering avsvenska innovationsmiljöer för hållbara städer.

    Toward an enzyme-based oxygen scavenging laminate.: Influence of industrial lamination conditions on the performance of glucose oxidase2002In: Biotechnology and Bioengineering, ISSN 0006-3592, E-ISSN 1097-0290, Vol. 79, no 1, p. 37-42Article in journal (Refereed)
    Abstract [en]

    The laminate consisted of several polymer layers, aluminium, and one cellulose-based layer containing the active enzymatic system (e.g., glucose oxidase, catalase, glucose, and CaCO3). During the industrial lamination process, the enzyme layer was exposed to three temperature spikes up to 325°C without significant enzyme inactivation. Ninety-seven percent of the glucose oxidase activity still remained after the lamination process. The best laminate had an oxygen absorbing capacity of 7.6 ± 1.0 L/m2. A reference that was not laminated expressed a corresponding oxygen absorbing capacity of 7.1 ± 0.8 L/m2. © 2002 Wiley Periodicals, Inc.

    Separated by a common language: Awareness of term usage differences between languages and disciplines in biopreparedness2013In: Biosecurity and bioterrorism, ISSN 1538-7135, E-ISSN 1557-850X, Vol. 11, no SUPPL. 1, p. S276-S285Article in journal (Refereed)
    Abstract [en]

    Preparedness for bioterrorism is based on communication between people in organizations who are educated and trained in several disciplines, including law enforcement, health, and science. Various backgrounds, cultures, and vocabularies generate difficulties in understanding and interpretating terms and concepts, which may impair communication. This is especially true in emergency situations, in which the need for clarity and consistency is vital. The EU project AniBioThreat initiated methods and made a rough estimate of the terms and concepts that are crucial for an incident, and a pilot database with key terms and definitions has been constructed. Analysis of collected terms and sources has shown that many of the participating organizations use various international standards in their area of expertise. The same term often represents different concepts in the standards from different sectors, or, alternatively, different terms were used to represent the same or similar concepts. The use of conflicting terminology can be problematic for decision makers and communicators in planning and prevention or when handling an incident. Since the CBRN area has roots in multiple disciplines, each with its own evolving terminology, it may not be realistic to achieve unequivocal communication through a standardized vocabulary and joint definitions for words from common language. We suggest that a communication strategy should include awareness of alternative definitions and ontologies and the ability to talk and write without relying on the implicit knowledge underlying specialized jargon. Consequently, cross-disciplinary communication skills should be part of training of personnel in the CBRN field. In addition, a searchable repository of terms and definitions from relevant organizations and authorities would be a valuable addition to existing glossaries for improving awareness concerning bioterrorism prevention planning. © 2013, Mary Ann Liebert, Inc.

    Slag-metal reactions during ladle treatment with focus on desulphurisation2002In: Ironmaking & steelmaking, ISSN 0301-9233, E-ISSN 1743-2812, Vol. 29, no 3, p. 224-232Article in journal (Refereed)
    Abstract [en]

    Within several cooperative projects, KTH (Royal Institute of Technology), Ovako Steel AB, and MEFOS have investigated the desulphurisation of bearing steel during vacuum degassing. The work includes thermodynamic calculations of the slag-metal equilibrium, CFD modelling of slag-metal reactions, and plant trials. Results from the various studies are presented and discussed in this paper. Models for predicting slag properties (sulphide capacity, viscosity, and oxide activities) in liquid slags as functions of slag composition and temperature have been used for the calculation of data which have been employed in static and dynamic modelling of sulphur refining. The results from static modelling show that the method allows fast and easy evaluation of the theoretical desulphurisation conditions during degassing at Ovako Steel AB, as well as theoretical determination of the parameters that have the greatest influence on the equilibrium sulphur distribution. The conclusion from dynamic modelling is that the vacuum degassing operation can be described dynamically with the present knowledge of sulphide capacity, sulphur distribution, viscosity, and oxide activities of ladle slags if this knowledge is combined with fluid flow modelling to derive the overall kinetics. The presented model approaches have been found useful in understanding the sulphur refining process at Ovako Steel AB. The dynamic modelling concept is also believed to have potential for dynamic descriptions of other slag-metal reactions in steelmaking. © 2002 IoM Communications Ltd.

    Peer-to-peer service sharing platforms: Driving share and share alike on a mass-scale2013In: International Conference on Information Systems (ICIS 2013): Reshaping Society Through Information Systems Design, 2013, p. 2964-2978Conference paper (Refereed)
    Abstract [en]

    The sharing economy has been growing continuously in the last decade thanks to the proliferation of internet-based platforms that allow people to disintermediate the traditional commercial channels and to share excess resources and trade with one another effectively at a reasonably low transaction cost. Whereas early peer-to-peer platforms were designed to enable file sharing and goods trading, we recently witness the emergence of a new breed of peer-to-peer platforms that are designed for ordinary service sharing. Ordinary services entail intangible provisions and are defined as an economic activity that generates immaterial benefits and does not result in ownership of material goods. Based on a structured analysis of 41 internet-based rideshare platforms, we explore and layout the unique characteristics of peer-to-peer service sharing platforms based on three distinct temporal patterns that entail specific consequences for platform use as well as provide insights about their overall design imperative. © (2013) by the AIS/ICIS Administrative Office All rights reserved.

    The mobile–stationary divide in ubiquitous computing environments: Lessons from the transport industry2005In: Information systems management, ISSN 1058-0530, E-ISSN 1934-8703, Vol. 22, no 4, p. 65-79Article in journal (Refereed)
    Abstract [en]

    The emergence of ubiquitous computing offers new possibilities and opportunities for organizations attempting to improve their productivity and effectiveness. in particular, the promises of ubiquitous computing are attractive to organizations such as transport firms, in which coordination of diverse sets of mobile units is central to organizational performance. This article analyzes the use of ubiquitous transport systems in Swedish road haulage firms and discusses the opportunities and challenges for the early adopters. It pays specific attention to the mobile–stationary divide; that is, the set of challenges associated with integration of mobile and stationary people and systems into a seamless computing environment.

    Architectural knowledge in inter-organizational IT innovation2008In: Journal of strategic information systems, ISSN 0963-8687, E-ISSN 1873-1198, Vol. 17, no 1, p. 19-38Article in journal (Refereed)
    Abstract [en]

    This paper examines the front-end process of inter-organizational IT innovation. In particular, it focuses on the nature and role of architectural knowledge. Such knowledge is important for development of architectures capable of serving the goals of heterogeneous actors and technologies. Yet, surprisingly little research has been done on how architectural knowledge may be developed through collective achievements. This paper presents a theoretical model of architectural knowledge development in inter-organizational IT innovation. Applying this model throughout an action research project within the Swedish transport industry, the paper identifies four dimensions of architectural knowledge that proved important for facilitating an industry-wide ubiquitous computing environment. The four dimensions are technology capability awareness, use context sensitivity, business model understanding, and boundary-spanning competence. We conclude the paper by outlining the theoretical and strategy implications of the model and the four dimensions of architectural knowledge. © 2008 Elsevier B.V. All rights reserved.

    Mapping and Evaluation of some Restricted Chemical Substances in Recycled Plastics Originating from ELV and WEEE Collected in Europe2019Report (Other academic)
    Abstract [en]

    Recycling of plastics is a critical step toward the realisation of a sustainable society. Plastic is a fitting material to recycle, as it often can easily be melted and formed into new products. Plastic recycling is therefore an easy process with pure plastics, however, most of the plastics that are recycled today are not pure and contain additives and/or impurities. Some of these additives can be hazardous substances that could be harmful for both humans and the environment. It is therefore important that these hazardous substances are not recycled and transferred into new products. To ensure a safe use of plastics, these substances are today regulated in new products, but old products could still contain these substances (legacy chemicals). To comply with legislation it is therefore critical that these substances are removed during the recycling process. There are however many hazardous substances that are yet not regulated, which may also be present in products and therefore recycled material. 

    Waste Electronic and Electrical Equipment (WEEE) and End-of-Life Vehicles (ELV) are two of the materials streams that contains a high amount of legacy chemicals. These streams have been associated with spreading legacy chemicals after recycling. In several reports WEEE plastics have been identified as the source of brominated flame retardants (BRF) found in toys and everyday items. According to the EU regulation the use of certain BFRs is not permitted in new products or articles above a certain value. Recyclers and resellers of the recycled plastic often specified that the products should not be used in toys, medical equipment of food contact application, yet BFRs from WEEE can still be found in these products. This could mean that either producers that use recycled material in new products do not follow the recommendations from the recyclers, or that the recycled material does not fulfil the regulations. Another possibility for the findings of legacy chemicals in these items could be a meagre follow-up on imported plastics.

    In this study the Research Institutes of Sweden (RISE) has, on behalf of the Swedish Environmental Protection Agency (Naturvårdsverket), investigated the content of legacy chemicals in recycled plastics that have been processed in a recycling facility. The plastics originated from WEEE and ELV and have been gathered from recyclers across Europe. A number of different legacy chemicals were investigated, both inorganic (Cd, Pb, Hg) and organic substances (flame retardants and plasticisers). To simulate a real case scenario and to get better measurement accuracy, all samples were injection moulded. The analysis of the samples was performed using X-ray fluorescence spectrometry (XRF), Inductively coupled plasma (ICP) and Gas chromatography with a Mass spectrometer (GC-MS). All the processing and analysis (except for SCCP/MCCP)) were done by RISE which gives good control over the analysis process, which are important when interpreting the results. In total 54 samples of PE, PP, ABS and PS, were gathered and tested. It was found that all but two samples contained legacy chemicals below the regulated values. The two samples that did not meet the legal limit had a HBCDD content above 100 ppm. All the tested materials contained detectable amounts of bromine, and 15 samples contained detectable amounts of regulated BFRs. None of the detected regulated BRFs were above 186 ppm.  Most of the materials also contained detectable amounts of cadmium and lead.

    Photochromic mesostructured silica pigments dispersed in latex films2005In: Journal of Materials Chemistry, ISSN 0959-9428, E-ISSN 1364-5501, Vol. 15, no 0149-2136, p. 3507-3513Article in journal (Refereed)
    Abstract [en]

    We have incorporated the photochromic dyes spiropyran and spirooxazine in surfactant templated mesostructured silica particles. Spherical inorganic–organic hybrid pigments with varying dye content were produced by a one-pot synthesis in an aerosol reactor where the internal mesostructure could be controlled. The mesostructured inorganic–organic hybrid pigments provide a mechanically and chemically rigid framework that protects the dyes and facilitate handling. We show that an organic latex binder can be used to prepare transparent photochromic films of varying thickness. Changing the dye loading in the pigments and the pigment content in the films provides a versatile route for tuning the photochromic response. The pigmented films show both fast and direct photochromism, where the decay time for thermal bleaching is very fast in the case of spirooxazine doped pigments (kSO= 0.094 s–1), being in the range of the best reported values for solid state composites.
