Abstract

Nowadays, corrosion is not only undesirable, but it also has a significant influence on the industrial sectors and technical innovations that have demand for metals. The global economic damage is expected to reach $2.5 trillion, equivalent to more than 3.4% of the world’s GDP in 2013. It is linked with significant financial harm, manufacturing pollution, and safety issues. An electrochemical process primarily induces metal corrosion at the metalelectrolyte interface region, caused by steel oxidation and the reduction of oxygen, protons, and water. Therefore, organic and epoxy coatings can be applied as protective coatings. Additionally, it can prevent metal corrosion in various fields due to its unique properties, like the ability to manage its curing process over a long period. This review paper focuses on improving the physicomechanical properties of modified graphene oxide (GO) coating by attaching a polymer, epoxy resin (EP). Moreover, we reviewed recent achievements for different methods in minimizing a corrosion phenomenon. Further, we considered the modification of epoxy resin using the curing agent as a bridge to the polymer to strengthen the functionalization of nanocomposites during the reaction. Afterward, we discussed the relationship between the modified GO/EP anticorrosive coating and physicomechanical properties since it is currently being questioned and remains unresolved. As a result, extensive studies on the mechanism of synthesis of the modified GO/EP anticorrosive coating were highlighted.
