  2. 2. Conjugated Polymer-based Conductive Fibers for Smart Textile Applications

    University dissertation from Chalmers University of Technology

    Author : Tariq Bashir; Högskolan i Borås.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Textil och mode generell ; Textiles and Fashion General ; electro-active fibers; poly 3; 4-ethylenedioxythiophene PEDOT ; viscose; polyester; chemical vapor deposition CVD process; electrical characterizations; smart textiles; stretch sensor; Organic Electronics; Smart Textiles; textile yarns;

    Abstract : Electrically conductive or electro-active fibers are the key components of smart and interactive textiles, which could be used in medical, sports, energy, and military applications in the near future. The functionalization of high-performance textile yarns/fibers with conjugated polymers can produce conductive fibers with better electro-mechanical properties, which is difficult with commonly used spinning techniques.

  4. 4. Electrically conductive textile coatings with PEDOT:PSS

    University dissertation from Borås : Högskolan i Borås

    Author : Maria Åkerfeldt; Högskolan i Borås.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; textile coating; conductive coating; conjugated polymers; ICP; PEDOT:PSS; textile properties; textile sensor; printed electronics; Smart textiles; poly 3; 4-ethylene dioxythiophene -poly styrene sulfonate ; Textil och mode generell ; Textiles and Fashion General ;

    Abstract : In smart textiles, electrical conductivity is often required for several functions, especially contacting (electroding) and interconnecting. This thesis explores electrically conductive textile surfaces made by combining conventional textile coating methods with the intrinsically conductive polymer complex poly(3,4-ethylene dioxythiophene)-poly(styrene sulfonate) (PEDOT:PSS).
