Abstract

Conductive polymers, such as polyaniline, which have conjugate structure and electrical properties, are attractive compounds for using in the electronic industry, anti-static coatings and anti-corrosive coatings. Due to their perfect electrical properties, they are widely used for various applications, especially polymer nanocomposites. In this study, the introduction of conductive polymers and their synthesis methods, fabrication of polymer nanocomposites and their anti-corrosion performance in organic coatings are discussed. The results showed that the presence of polyaniline in the organic coating formulations cuased a thick and dense iron oxide layer formation on the metal surface so that this coating did not only improve the adhesion of the epoxy coating to the substrate and prevent the cathodic delamination, but also the development of corrosion products under the coating can be limited because of the active role of polyaniline.
