Research Progress of Polymer‐Based Coatings for Anti‐Corrosion Application: A Mini Review

ABSTRACT Corrosion is a complex electrochemical process, resulting in the degradation of metal, and reducing lifespan, strength, and durability. The main objective of this review highlights the need for polymer‐based coatings to protect metal substrates and reduce the environmental and economic impact. This review focuses on research progress and development trends of polymer‐based coatings and highlights their roles in corrosion resistance on different metal substrates. This case study elucidates the effectiveness of the polymer‐based coatings in preventing metal substrates from corrosion. In addition, this review demonstrates various protective methods from corrosion, focusing on polyurethane coatings, epoxy coatings, polyester coatings, polyacrylic coatings, and biopolymer coatings to enhance corrosion resistance. Ultimately, it summarizes the challenges associated with practical applications of marine anti‐corrosive coatings to protect against marine corrosion and offers a future outlook and direction for anti‐corrosive coating development.
