A processable electrically conductive polymeric complex comprising a polyelectrolyte having acid functional groups and a conductive polymer selected from the group consisting of polyaniline, polypyrrole, polythiophene, poly(phenylene sulfide), the conductive polymer ionically bound to the polyelectrolyte. The mole ratio of the monomers which form the conductive polymer to the acid functional groups of the polyelectrolyte is ≧1. The polymeric complex is made by a template-guided chemical polymerization process which comprises adsorbing the monomers onto the polyelectrolyte in a mixture of alcohol and water to form a polyectrolyte adduct, emulsifying the polyelectrolyte adduct in an acid to form an emulsified polyelectrolyte adduct and oxidatively polymerizing the emulsified polyectrolyte adduct. The polymeric complex is water insoluble when dried as a coating on a substrate.
