Overview: Polypyrrole-polystyrene sulfonic acid (PPy-PSSA) composite films have been electro synthesized in an aqueous solution of PSSA. The electro-active films exhibit cation exchange during the redox process. Infrared, Raman and energy dispersive spectroscopic results demonstrated that the polyanion of PSS- is co-deposited into the PPy matrix and couldn't be stripped from the film extensively by dedoping. SEM images revealed that the composite film has smooth and compact morphology and AFM pictures suggested that PPy chains are possibly grown perpendicular to the electrode surface.
