Özet

Polypyrrole films are formed on low-carbon steel by electropolymerization in solutions of oxalic acid. Their morphology and corrosion properties are studied by the methods of scanning electron microscopy and dc polarization. Polypyrrole coatings increase the corrosion potentials and decrease the corrosion currents in neutral solutions of chlorides and basic solutions.
