Corrosion protection of steels: a brief review on conductive polymers

Abstract

The conventional anticorrosive coatings which are based on heavy metals such as chromium, zinc and copper are toxic to the environment. There has been a need to find suitable replacement coatings to be environmentally friendly and effective to inhibit corrosion of steels. Conductive polymers have acquired more attentions in the last years due to their environmentally benign nature and high effectiveness to protect steels against corrosion. Owing to their redox properties, conductive polymers can interact with the steels, forming a compact layer to protect the substrate surface against corrosion. Present brief review paper try to summarize study on conductive polymers and their anticorrosive properties. The following concepts are discussed sequentially in this paper: corrosion protection using conductive polymers and conductive polymer applying methods on steels
