Effects of polymolybdate on pyrrole and aniline electropolymerization and electrochemical performance of polymer films containing polymolybdate anions as dopants are investigated with the cyclic voltammetry method. The number of molybdenum atoms in the polymolybdate anion, which is predominantly contained in the electrolyte and is incorporated into the synthesized polymer film as a doping agent, depends on the ratio of the acid and molybdenum concentrations. Polymolybdate has been shown to accelerate the film growth and extend the redox capacity of the film. These two effects are due to high electrochemical activity of polymolybdate. During the process of polymer-film cycling, the polymolybdate anion is easily removed out of polypyrrole into electrolyte but remains firmly immobilized in polyaniline, presumably forming a complex with the latter.
