Abstract

A conductive polymer composite, comprising a polymer and polypyrrole and derivatives thereof. The composite is manufactured by first diffusing an oxidant such as iodine into the polymer, and then diffusing pyrrole or a pyrrole derivative vapor into the impregnated polymer, resulting in an in situ chemical oxidative polymerization of pyrrole at the oxidant site. The conductivity of the composite foam can be effectively controlled between 10−7 to 10−1 S/cm, inclusive.
