Abstract

A layer of electrically conductive polymers is applied by a process in which carbon fibers of filaments or sheet-like structures of carbon fibers or filaments are coated with sulfonic acids of phthalocyanines or porphyrins, the filaments treated in this manner are made the anode in a solution which contains monomers from the class consisting of the 5-membered heterocycles, and the monomers are anodically polymerized so that a conductive layer is formed on the fibers, filaments or sheet-like structures.
