Recent advances in corrosion protective composite coatings based on conducting polymers and natural resource derived polymers

Conducting polymer (CP) coatings have been extensively investigated for corrosion protection of iron, steel and other metals owing to their superior performance in highly aggressive environments and ecofriendly characteristics. Corrosion protective coatings based on CP nanocomposites have opened a new area of research for obtaining low cost coatings with enhanced performance and tailored properties. This mini review highlights the latest developments in the corrosion protective performance of CP composite coatings with natural resource derived polymers. The presence of nanoscale dispersion of CP as filler significantly improves the barrier properties and lifetime of the organic polymeric coatings. These low-cost nanocomposite coatings are expected to play an important role in combating corrosion which can lead to drastic improvement in corrosion protection. (C) 2014 Elsevier B.V.
