Conducting nylon, cotton and wool yarns by continuous vapor polymerization of pyrrole

Abstract

Conductive textile yarns were prepared by a continuous vapor polymerization method; the application of polypyrrole by the continuous vapor polymerisation method used is designed for the easy adaptation into industrial procedures. The resultant conductive yarns were examined by longitudinal and cross-sectional views, clearly showing the varying level of penetration of the polymer into the yarns structure. It was found that for wool the optimum specific resistance was achieved by using the 400 TPM yarn with a FeCl 3 solution concentration of 80 g/L FeCl 3 to produce 1.69 Ω g/cm 2. For cotton yarn, the optimum specific resistance of 1.53 Ω g/cm 2 was obtained with 80 g/L of a FeCl 3 solution.

Integrating high electrical conductivity and photocatalytic activity in cotton fabric by cationizing for enriched coating of negatively charged graphene oxide

“…However, these techniques come at the cost of reducing the required flexibility of the fabric. On the other hand, other techniques such as extrusion of fibers with conducting particles, such as carbon derivatives, and synthesis of conducting polymer films on the fabric (Kaynak, Najar, & Foitzik, 2008) does not provide highly conductive textile materials. Therefore, impregnating textiles with materials like intrinsically conducting polymers, carbon nanotubes, graphene or metal based powders are being seen as alternatives (Hu et al, 2010;Molina, del Río, Bonastre, & Cases, 2008;Molina, Fernández, del Río, Bonastre, & Cases, 2013).…”

Chemical and electrochemical study of fabrics coated with reduced graphene oxide

“…Different methods have been employed to provide the fabrics with electrical conductivity. For example the use of metallic fibers inserted in the fabric, chemical metallization of fibers [5], the extrusion of fibers with conductive particles such as carbon derivatives [6] or the synthesis of conducting polymer films on the fabrics [7][8][9].…”

Nanocomposite coatings on cotton and silk fibers for enhanced electrical conductivity

“…Electrically conducting coatings on yarns and fibers offer better strength and low surface resistivity [11,12]. These fibers and yarns can be used as flexible conductive structures in the fields of sensors, heated fabrics, electromagnetic shielding, smart clothing, thermal storage, microwave absorption and intelligent textiles [1,13].…”
