    Författare :Ann Pontén; Yrkes- och miljödermatologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thin-layer chromatography; occupational dermatitis; isomers; bisphenol F; bisphenol A; DGEBF; DGEBA; epoxy resin of the bisphenol F-type; Epoxy resin; contact allergy; Dermatology; venereology; Dermatologi; venereologi; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

    Sammanfattning : Epoxy resins based on bisphenol A are well-known contact allergens and often cause occupational contact allergy. The most important allergen is the monomer diglycidyl ether of bisphenol A (DGEBA). LÄS MER

  3. 2. Exploring fatty acid derivatives from renewable resources as raw materials for coating applications

    Författare :Samer Nameer; Mats Johansson; Mats Martinelle; Dean Webster; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epoxy; vegetable oils; birch bark; thermoset; bio-based; fatty acid; renewable resources; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : In the work presented herein, epoxy fatty acid derivatives were explored in the formation of thermosets for coating applications. The epoxy fatty acid derivatives were obtained from renewable resources such as birch tree bark and epoxidized linseed oil. LÄS MER

  4. 3. Compression-moulded and multifunctional cellulose network materials

    Författare :Sylvain Galland; Lars Berglund; Naceur Belgacem; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compression-moulding; cellulose fibre; nanocomposite; magnetic nanoparticle; epoxy; UV curing; oxygen barrier;

    Sammanfattning : Cellulose-based materials are widely used in a number of important applications (e.g. paper, wood, textiles). Additional developments are suggested by the growing interest for natural fibre-based composite and nanocomposite materials. LÄS MER

  5. 4. Studies of Dielectric Relaxation in Solid Polymers and Composites

    Författare :Mohsen Safari Ardi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dielectric permittivity; time-domain dielectric relaxation; composite; carbon black; poly vinylidene fluoride ; interfacial polarization; poly vinyl chloride ; coated carbon fibre; epoxy; poly methyl methacrylate ; nitrile butadiene rubber; ethylene-vinyl acetate copolymer; polyamide 6;

    Sammanfattning : Non-linear characteristics of homogeneous solid polymers and solid polymer-based composites have been studied both experimentally and theoretically. In particular experimental studies of non-linear dielectric response of six homogeneous solid polymeric materials and the influence of the composition on the properties of solid polymer-based composites with high dielectric permittivities have been carried out and a theoretical study of dipole-dipole interaction in solids based on a formulation due to P.

  7. 5. High Clay Content Cellulose Nanocomposites for Mechanical Performance and Fire Retardancy

    Författare :Lilian Medina; Lars Berglund; Jeffrey W. Gilman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanocellulose; nanofibril; nanofiber; CNF; nanoplatelet; nanostructure; tactoid; montmorillonite; MTM; foam; aerogel; porosity; PVA; poly vinyl alcohol ; epoxy; moisture; biocomposite; biomaterial; biobased; flame; cone calorimetry; gas barrier; coating; film.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Materials based on wood can offer sustainable alternatives to fossil-based plastics and composites, and show interesting mechanical properties. However, the issue of their flammability is generally unresolved. In this thesis, eco-friendly, fire retardant clay-cellulose nanofibril materials are investigated. LÄS MER
