摘要：

A series of electrochemical measurements, including corrosion potential, corrosion current, Tafel's constants and polarization resistance, have been made on polyaniline-coated cold rolled steel specimens under various conditions. Both the base and acid-doped forms of polyaniline were studied. The base form of polyaniline was found to offer good corrosion protection. This phenomenon may not originate merely from the barrier effect of the coatings, because nonconjugated polymers such as polystyrene and epoxy did not show the same electrochemical behaviour.
