2. 1. Melt Spun Electro-Conductive Polymer Composite Fibers

   Author : Azadeh Soroudi; Högskolan i Borås; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conductive fibres; composites; blending; melt spinning; morphology; polyaniline; carbon nanotube; polypropylene; polyamide; draw-ratio; conductivity; Energi och material;

   Abstract : One interesting approach is the development of conductive polymer composite fibers for innovative textile applications such as in sensors, actuators and electrostatic discharge. In this study, conductive polymer composite fibers were prepared using several different blends containing conductive components: a conjugated polymer (polyaniline-complex) and/or carbon nanotubes.
