ABSTRACT
The intrinsically conducting polymers have been a hot topic since their first appearance, attracting considerable attention from various areas, due to their easy synthesis, fewer toxicological problems, stability in oxidized form, high electrical conductivity, good redox properties, and the processability of conventional polymers. The developments in nanomaterials and nanotechnology have extended the potential allocation of conducting polymers and their nanocomposites. Conducting polymers, as a new corrosion-control methodology, have attracted more and more attention from researchers and related enterprises, owing to their excellent protective performance and environmental moderate feature, especially under the requirement of sustainable development of the social environment. Polyaniline was considered an efficient and eco-friendly candidate for the replacement of chromates (CrO4 2−) to provide corrosion protection of steels. Herein, the uses of conducting polymers in corrosion protection and corresponding protective mechanisms are summarized.
