Epoxy resin coating is widely used in the field of metal anti-corrosion because of its excellent corrosion resistance and good adhesion to metal surface. However, defects and holes will be formed during the curing process of the coating film, and the corrosive medium can directly contact the metal surface. In order to develop excellent and durable anti-corrosion coatings, the researchers prepared a variety of epoxy resin anti-corrosion coatings using different methods and materials. This review introduces the preparation and properties of nanoparticle-modified epoxy anti-corrosion coatings, superhydrophobic epoxy anti-corrosion coatings, self-healing epoxy anti-corrosion coatings, conductive polymer-modified epoxy anti-corrosion coatings and bio-based material modified epoxy anti-corrosion coatings. However, these kinds of anti-corrosion coatings have their own limitations, and new epoxy anti-corrosion coatings should be explored in the future, which can improve the anti-corrosion performance of the coating while taking into account other properties, so that epoxy-based anti-corrosion coatings will develop in the direction of functional intelligence.
