As a key means of protection,anti-corrosion coatings are widely used to extend the life of materials and structures and protect them from corrosion and damage.However,a single anticorrosive coating is often difficult to meet the multiple challenges in complex environments.In order to overcome the limitation of tradi-tional anticorrosive coating,people began to seek new anticorrosive coating technology,functional composite anticorrosive coating came into being.The research progress,preparation methods,properties and practical ap-plication of anti-corrosion coatings are introduced.The types and composition of functional composite anti-corro-sion coatings are described,the current status of functional composite anti-corrosion coatings is analyzed and summarized,and its application prospect is prospected.
