Corrosion Protection Behavior of Carbon Nanotube-based Nanocomposite

Polymer coatings have been successfully employed in corrosion protection of metals. In this article, the polymer coatings containing carbon nanotube have been focused for anti-corrosion behavior. Epoxy-based coatings have gained significant research interest owing to sufficient hydrophobicity, conductivity, water transport behavior, and corrosion resistance. According to corrosion resistance studies, incorporation of nanotube may increase the corrosion resistance owing to filling of microspores prone to corrosion attack. The anti-corrosive polymer coatings with low nanotube content have shown enhanced surface hydrophobicity and anti-rusting properties in addition to strength, conductivity, and thermal resistance
