ABSTRACT:
A process for preparing a conductive polymer article comprises the steps of preparing a dispersible neutral intrinsically conductive polymer; dispersing the intrinsically conductive polymer in a thermoplastic polymer to form a blend; processing the blend into the shape of the desired article; and, contacting the processed article with a dopant solution capable of both swelling the thermoplastic polymer and doping the intrinsically conductive polymer. A process for preparing neutral polyaniline comprises the steps of neutralizing doped polyaniline with a sodium carbonate solution and washing the polyaniline with a polyethyleneglycol solution. A conductive polymer article comprises a blend of an intrinsically conductive polymer and a thermoplastic polymer which is subsequently doped. A conductive polymer blend according to the invention, includes polyaniline, or insulating thermoplastic material and carbon black.
