Recent development in polymer coating to prevent corrosion in metals: A review

Abstract

Corrosion in metals is a pervasive and costly issue across various industries, from infrastructure to manufacturing. Corrosion is a complex electrochemical process, and mitigating it is paramount to extend the lifespan and maintain the integrity of metal structures and components. This review study provides a thorough overview of the state-of-the-art use of polymer coatings to stop metal corrosion. It then delves into polymer coatings’ essential properties and advantages, highlighting their role in corrosion inhibition. The paper surveys recent advancements in polymer coating techniques and their compatibility with different metal substrates. The case studies and real-world applications where polymer coatings have been successfully employed to prevent corrosion in diverse settings, including marine environments, automotive components, and aerospace structures, are explored. Case studies illuminate the efficacy of these coatings, showcasing their role in safeguarding assets, reducing maintenance costs, and promoting sustainability. By analyzing these cases, the paper elucidates the practical effectiveness of polymer coatings in corrosion prevention. This review article addresses numerous ways of shielding metals from corrosion, focusing on nanomaterials, conducting polymers, nano-composites, and carbon-based materials for corrosion resistance. This literature review stands out for its thorough analysis of the most recent developments in this field and the ways in which various polymer coatings are being used to prevent corrosion.
