Heat generation in Electrically Conductive Polypyrrole Coated Cotton Fabric

In situ polymerization was employed to deposit polypyrrole (Ppy) on the cotton fabrics by using ferric chloride as oxidizing as well as doping agent. The Ppy coated cotton fabric showed conductivity of about 0.21S/cm. When subjected to a constant DC voltage of 10V, owing to considerable resistance the temperature of Ppy coated fabric increases rapidly up to 60°C. Further, the repetitive heating showed reduction in conductivity to 0.11S/cm. The polypyrrole coated cotton fabric has many potential applications like medical or warmth clothing, heating pads.
