Abstract (EN): Electropolymerisation of pyrrole on Zinc -lead - siver (Zn-Pb-Ag) alloys was carried out in acetonitrile, nitrobenzene and propylene carbonate (PC)organic media in presence of para-toluene sulfonate counter ions. Adherent and homogenous PPy films have been obtained on zinc alloy electrodes (65%Zn, 10% Pb and 25% Ag) prealably treated with aqueous sodium sulfite solution. The galvanostatic mode was proved to be better adapted to perform the electrosynthesis of polypyrrole using low applied current densities.
