ABSTRACT:
Electrically conductive composites comprising a dielectric porous substance, e.g. fiberglass fabric, and a pyrrole polymer deposited in the pores of such substance. The composites are produced by contacting the porous substance with an anode in an electrolytic cell containing an electrolyte comprising a pyrrole monomer and a substantially non-nucleophilic anion such as bisulfate, and passing an electric current through the cell, thus electrochemically precipitating a conductive pyrrole polymer in the pores of such substance.
