Abstract
Vapor deposition technique was employed to coat polypyrrole (PPy) on glass substrate using FeCl3 as oxidant and p-toluenesulfonic acid (−OTs) as doping agent. The Joule heating effect of PPy coated E-glass fabric was studied by supplying various DC electric fields. The coated fabric exhibited reasonable electrical stability, possessed medium electrical conductivity and was effective in heat generation. An increase in temperature of conductive fabric subjected to constant voltage was observed whereas decrease in power consumption was recorded. Thickness of PPy coating on glass fibers was analyzed by Laser confocal microscope and scanning electron microscope.

Current will flow through these fabrics without any wiring through them and the heat generated is not affected by holes or cuts in the fabric as the entire surface is electrically conductive
Summary
In the late 1970s, MacDiarmid, Heeger, and Shirakawa discovered how to get polymers conducting electricity [1]. The first material becoming an intrinsically conducting polymer (ICP) was polyacetylene, after a doping with iodine. The announcement of this discovery quickly reverberated around scientific communities, and intensity of the research for other conducting polymers magnified dramatically [1,2,3]. Each fiber on the surface of the textile is coated by a thin layer of conducting polymer. As a result of chemical polymerization in the presence of a fabric, a continuous thin film of conducting polymer is formed on the fabric surface. Current will flow through these fabrics without any wiring through them and the heat generated is not affected by holes or cuts in the fabric as the entire surface is electrically conductive
