Metal corrosion is an irreversible destructive behavior, therefore, the research of anticorrosive coatings has become a vital research topic in various fields. With the development of recent years, the single protective form of anti?corrosion coating is no longer sought after, the advent of barrier/self-healing coatings has added a significant complement to anti?corrosion coatings and has become one of the most widely studied topic today. Subsequently，new anti-corrosion forms such as ion exchange, hydrophobicity and intelligent self-warning have appeared on the market. Dual/multi-functional anti?corrosion coatings that integrate self-healing, barrier properties, hydrophobic properties and intelligent self-warning properties have also become research topics in recent years. In this paper, the research progress of barrier/self-healing bifunctional anti?corrosion coatings, other dual-function anti-corrosion coatings (ion exchange/self-healing coatings, hydrophobic/self-healing, self-warning/self-healing) and multi-functional anti-corrosion coatings are reviewed, and the future development direction of more intelligent and green dual/multi-functional coatings is prospected.
