Research Progress on Metal‐Organic Framework Materials in Corrosion‐Resistant and Antimicrobial Metal Functional Coatings

ABSTRACT Metal‐organic frameworks (MOFs) hold significant potential across numerous advanced disciplines due to their exceptional properties, including high specific surface area, tunable porosity, structural diversity, and customizable functionality. Increasing attention has been directed toward employing MOFs in coatings that offer both antimicrobial activity and corrosion resistance. This review systematically summarizes the novel applications of MOFs in protective coatings for metal surfaces, with an in‐depth discussion of preparation techniques, microscopic structural regulation, protective performance, and mechanisms underlying corrosion resistance and antimicrobial action. Studies demonstrate that MOF‐based protective coatings fabricated through various methods can substantially enhance the corrosion resistance of metal substrates. Regarding antimicrobial activity, the synergistic and complementary effects of two primary mechanisms are emphasized: sustained release of metal ions achieves long‐term antibacterial activity, whereas photodynamic/photothermal effects enable rapid sterilization and biofilm disruption. Despite significant advances in dual‐protection applications using MOFs, critical technical challenges persist, including complex fabrication processes, cost management difficulties, limited biocompatibility, and insufficient long‐term stability. Future research should focus on optimizing fabrication protocols, reducing costs, improving biocompatibility, and enhancing long‐term stability to enable the widespread industrial application of these intelligent protective materials in high‐end equipment manufacturing and biomedical engineering.
