Polymer Nanocomposites Coating for Anticorrosion Application

Corrosion is the foremost reason for the deterioration of metallic components used in harsh environments and hence research on the development of an innovative protective system with admirable performance has become a subject of leading importance. Currently, chromates free organic or the polymer coatings on the metal substrate bestow an efficient barrier amongst the metal and inhibit corrosion and save the environment. Researchers have involved in the development of polymer coating containing nanoparticles because reinforcement of nanoparticles decreases the porosity and provides a zig-zag diffusion path which in turn forms barrier layer on the metal surface to protect the metal from the harmful corrosive species. This present chapter deliberates the application of polymer-based nanocomposite coating to mitigate the corrosion of metals against harsh environment. This chapter covers the utilization of carbon-based nanoparticles, inorganic nanoparticle, conductive polymer, self-heling polymer, etc., and could shows a new insight to for anti-corrosive metal surface protective coating.
