Electropolymerization of pyrrole and characterization of the obtained films

It is possible to produce polypyrrole films on mild steel by electropolymerization from aqueous solutions. The present study compares the characteristics of films obtained from various solutions (Na2SO4, H2C2O4, Na2C2O4 or H3BO3) on mild steel. Films are studied by Scanning Electron Microscopy, Optical Microscopy, Auger Electron Microscopy, X‐Ray Photoelectron Spectroscopy and Fourier Transform Infrared Spectroscopy. Other studies are under way on galvanized steel and zinc.
