ABSTRACT:
Production of electrically conductive composite or structural materials comprising a dielectric substrate, e.g. fiberglass fabric, and a layer of a pyrrole polymer on the substrate, by treating the substrate with a solution of a strong oxidant containing a substantially non-nucleophilic anion, e.g. ferric chloride, drying the substrate and exposing the so treated substrate with the vapors of a pyrrole and oxidizing the pyrrole by the strong oxidant and depositing a polypyrrole layer or film on the substrate.
