Resumo: The influence of acidity on the synthesis and redox behavior of polypyrrole films was studied using galvanostatic and potentiodynamic techniques employing aqueous solutions formed by H2SO4/Na2SO4 , HCl/NaCl and HCl/CsCl. The chemical structure of the films were investigated using the FTIR technique. The polymer behavior as a function of the pH used in the cyclic voltammetric measurements is explained in terms of the mechanism responsible for the charge compensation formed during the polymer chain oxidation. From the FTIR measurements, it is seen that the water nucleophilic attack during the synthesis, does not occur under the experimental conditions employed in this work.
