STUDY OF KINETIC FORMATION AND THE ELECTROCHEMICAL BEHAVIOR OF POLYPYRROLE FILMS

Polypyrrole films have been electrochemically polymerized on platinum electrode under different conditions. The effect of the parameters used during the potentiostatic polymerization, such as monomer concentration, type of doping agent (i.e. counterion), deposition time (i.e. films thickness), conce...
