ABSTRACT
Recent studies demonstrate that incorporating nanomaterials into metallic coatings can help prevent corrosion while also prolonging the life of the coating. Due to their corrosion-resistant qualities, two-dimensional (2D) carbon nanostructures such as graphene and graphene oxide have lately garnered considerable interest. These nanomaterials, once introduced to the metallic surface, exhibit exceptional performance as a barrier to corrosive ions and can serve as containers for adsorbed corrosion inhibitors. The application of graphene and graphene oxide, as well as their numerous forms and functionalised derivatives, in corrosion protection, namely in the areas of anticorrosion coatings and corrosion inhibition, are discussed through several examples in this chapter. Due to their “barrier effect,” unique properties, and extremely high chemical stability, graphene and graphene oxide composite coatings are more resistant to corrosion than traditional coatings. Newly found 2D insulating materials will allow for a large increase in the manufacture of corrosion-resistant materials. In addition, it would be advantageous to create new materials and expand the scope of the category of graphene-like materials.
