Method of stabilizing conductive polymers

摘要

A method of stabilizing electrically conductive polymers to hostile environments is disclosed. The method comprises encapsulating the conductive polymer, e.g., polypyrrole or polyaniline, as a powder, a free-standing film or preferably in the form of a composite of a substrate, such as fiberglass fabric, impregnated with the conductive polymer, with a suitable resin, preferably an epoxy resin, as an encapsulating agent. The preferred method involves pre-pregging the fabric of the conductive composite with an epoxy resin and curing the resulting system.
