Abstract
The presence of pyridinium chlorochromate as an oxidizing agent in ace tonitrile solution containing the monomer and the doping agent signifi cantly accelerates electrochemical polymerization of pyrrole. The thic kness of polypyrrole layers produced by this combined electrochemical and chemical synthesis reaches several milimetres for the 60 min polym erization reaction. The influence of pyridinium chlorochromate concent ration on the rate of polymer formation and the amount of released gas was investigated during the combined synthesis of polypyrrole. The po lypyrrole prepared was characterized by ESCA analysis.
