Abstract
A composite is formed wherein particles of a conductive polymer are uniformly distributed within a processable non-conductive polymer. In the method of the invention, an inverted emulsion is formed by dispersing an aqueous solution of oxidant in an organic solvent comprising a host polymer and an oil-soluble surfactant. A monomer whose polymerization yields a conductive polymer which is dissolved in a solvent miscible with the organic solvent of the emulsion is then added dropwise to the emulsion with agitation. The composite is separated from the emulsion and the precipitate is washed and dried.
