A review of corrosion resistance in steel alloys with MOF-embedded coatings

Steel is widely used due to its strength, cost-effectiveness, availability, ease of fabrication, ductility, and design flexibility. However, corrosion is a significant challenge, especially in outdoor environments, leading to gradual degradation. Applying coatings to steel and its alloys is an effective way to protect them from corrosive media. Recently, researchers have explored using metal-organic frameworks (MOFs) in protective coatings for various metal alloys. MOFs, hybrid crystalline materials made of metal ions (or clusters) bonded to organic ligands, have gained substantial interest in both organic and inorganic chemistry. They exhibit remarkable characteristics, such as high specific surface area, tunable structure and functionality, well-organized pore arrangement, and abundant active sites, making them promising anticorrosion materials. This review paper focuses on recent research developments in MOF-based corrosion protection materials and assesses their effectiveness in preventing corrosion.
