Electrochemical synthesis of polypyrrole films (PPy) on aluminum surfaces from oxalic acid aqueous solutions was performed using the cyclic voltammetry and galvanostatic technique. SEM micrographs of aluminum surfaces coated with PPy films showed that the galvanostatically deposited films were more homogeneous than those deposited by cyclic voltammetry. The presence of bands at 1170 and 1630 cm-1...
