Abstract : Polypyrrole films have been electrodeposited on stainless steel electrodes. We precise here the limits current density, temperature in which a conductive film can be obtained. The ratio of the electronic conductivity perpendicular to the film surface over the electronic conductivity parallel to the film surface is smaller than 103. The dependance of the perchlorate ions diffusion coefficient versus temperature corresponds to an activation energy of 30 kJ-mole.
