Structure and amounts of counter ions in polypyrrole films prepared from aqueous solutions of sodium tosylate

A series of conducting polypyrrole films was prepared from aqueous TsONa solution of different concentrations, and investigated by means of elemental analyses and scanning electron microscopy. The results show that the different concentrations of the supporting electrolyte TsONa do not only cause different amounts of counter ions in the film, but also cause a different structure and morphology of the film.
