Published in Synthetic Metals 2007

Abstract

A polyaniline (PAn) containing coating layer leads to substrate corrosion in an environment of aggressive anions. A cationic coating results in delamination or blistering. A bipolar coating consisting of a PAn primer and a cationic topcoat inhibits both corrosion and delamination.
