Abstract

The invention concerns a method of manufacturing highly conducting composites, the method being characterized by the following steps: a) contacting a powder or fibers with an aqueous solution containing an appreciably water-soluble high-molecular substance, b) optionally washing with water, c) contacting with a dispersion containing finely particulate electrically conducting material, wetting agents (surfactants) and an ionogenic metal compound, d) optionally washing with water and e) molding to required shape.
