ABSTRACT:
Fabrics are made electrically conductive by contacting the fiber under agitation conditions with an aqueous solution of a pyrrole compound, an oxidizing agent and a doping agent or counter ion and then depositing onto the surface of individual fibers of the fabric a prepolymer of the pyrrole compound so as to uniformly and coherently cover the fibers with a conductive film of the polymerized pyrrole compound and wherein, furthermore, the oxidizing agent is a ferric salt and the aqueous solution further contains a weak complexing agent for ferric ions to effectively control the reaction rate such that the prepolymer is uniformly and coherently adsorbed onto the surface of the textile material, thereby providing improved films of electrically conductive polymerized compound on the textile material.
