Abstract: Copper, one of the most frequently utilized non-ferrous metals, finds extensive applications in the electrical industry, mechanical engineering, construction industry, and arm production. Long-term exposure to corrosive environments including moisture, sulfur, chlorine, and microbes induces corrosion, a significant factor contributing to material deterioration. Consequently, numerous scientific endeavors have been directed towards the prevention of copper corrosion. Notably, coating copper with innovative materials like graphene, boron nitride, and various conductive polymers has proven effective in thwarting corrosion. Additionally, the introduction of new organic compounds, including azole derivatives, amino acids, and N-heterocyclic carbenes, has bolstered the eco-friendliness and efficiency of corrosion inhibitors and molecular passivation techniques. Furthermore, these approaches have been extensively investigated for their efficacy in antioxidation of copper nanomaterials. This study provides a comprehensive review of the latest advancements in protective technologies, such as anti-corrosion coatings, corrosion inhibitors, and molecular passivation layers, aimed at countering copper corrosion under aggressive conditions.
