Cotton fabric coated by polypyrrole -effect of temperature on conductivity

摘要

Electrically conductive fabrics are one of the most important of smart/technical materials and these can be obtained when treated with intrinsically conducting polymers (ICPs) which have received considerable attention of scientists because of its good environmental stability and its application in different areas such as manufacturing of organic transistors and light-emitting diodes [1], functional textiles [2], organic electrodes [3], coatings for fuel cells and corrosion protection [4] and biosensors [5]. The most prominent ICPs are polypyrrole and polyaniline, where electrical conductivity can have values comparable to those observed for poorly conducting metals and alloy [6]. ICPs are conjugated polymers, with alternating single and double bonds in the polymer backbone, a necessary condition for charge carriers to move freely along the chain when doping is provided.
