ABSTRACT

A destructive phenomenon, corrosion is believed to undermine the long-term endurance of infrastructures and causes significant financial and structural damage to industrial units and buildings. Out of various strategies utilised for saving the infrastructure from corrosion, using protective coatings to shield metal surfaces from corrosion is one of the most effective methods. Further, carbon's ability to have various oxidation states or coordination numbers is responsible for the formation of a large variety of allotropic forms. In this chapter, these carbon allotropes, including graphene, graphene oxide, single-walled carbon nanotubes, multi-walled carbon nanotubes, etc., are investigated for their corrosion protection behaviour for various metals. Carbon allotropes play a critical role in the development of hydrophobic metal alloy coatings. Carbon allotrope-based coatings are one of the most efficacious, cost-effective, and environmentally friendly materials available in recent times.
