Abstract

The elcctrochemical  polymerization of pyrrole (Py) in aqueous KN03 solutions using Austenitic stainless steel electrodes by galvanostatic, potentiostatic and potentiodynamic methods was studied. Chronoamperometric experiments show different behavior of the current with time. Correspondingly, 1-tx plots were made giving better fitting for x =3/2 suggesting a progressive nucleation with three-dimensional growth and, for x =-l /2 which indicate that diffusion is limiting the growth of the film. Chronopotentiograms are typical of a conducting polymer without any sign of passivation and, potentiodinamic curves indicate an irreversible electrodeposition.
