  5. 9. Functional Textile Coatings Containing Flake-shaped Fillers : investigations on selected optical and electrical properties

    Författare :Veronica Malm; Ilda Kazani; Högskolan i Borås; []
    Nyckelord :Flakes; fillers; textile coating; properties; multilayered mica; effect pigment; angle-dependent colour change; metals; conductivity; resistance measurements; e-textiles; flexibility; durability; Textil och mode generell ; Textiles and Fashion General ;

    Sammanfattning : This thesis investigates the manufacturing and characterisation of functionalised textile coatings containing different types of flake-shaped fillers with angle-dependent colour-changing and electrically conductive properties, respectively. Common benefits of these types of flakes are their high aspect ratio, which offers low filler loading with high functional performance. LÄS MER
