dc.description.abstractElectrochemical potentiodynamic polarisation supported by SEM morphological examinations have been used to evaluate a range of electrochemically deposited polyanilines and also multilayered coatings, consisting of combinations of the conducting polymers polyaniline and polypyrrole for use in inhibiting corrosion, in particular 304L stainless steel and carbon steel. It was found that emeraldine salt coatings provided superior protection compared to their base counterparts. For Multilayer coatings, it was found that the degree of protection was a function of the deposition order of the copolymer, with films consisting of a polyaniline layer over the top of a polypyrrole layer yielding the best results. The ability of a conducting polymer film to act as electronic and chemical barriers were more important in providing corrosion protection than its ability to act as a physical barrier. Hence, conducting polymers can be used as an alternative film forming corrosion inhibitors or as in protective coatings.
