Broadly, the research work concerns functionalized carbon materials for corrosion resistance coatings on metal alloys. Newly design organic molecules were synthesised and functionalized with graphene oxide for improved inhibition efficiency and stable corrosion resistance in aggressive environments. The long-term stability of organic inhibitor molecules is useful as conventional inorganic alternatives can fail in aggressive environments. However, some organic inhibitor molecules cause damage to the environment if they are made from non-biodegradable organic molecules. Heterocyclic compound-functionalized graphene oxide and imidazole-functionalized graphene oxides act as ‘green’ inhibition coating materials for Mg alloys, mild steel, and titanium as they are biodegradable.
