To meet the requirements for long-term corrosion protection in marine environments，current research mainly focuses on high-performance intelligent response corrosion protection coatings，and the design and development of composite coatings with early damage self-warning and self-healing functions. In this paper，the latest research progress on intelligent anti-corrosion coating materials in harsh marine environments were reviewed，mainly including self-healing corrosion protection coating and self-warning corrosion protection coating，and the key factors affecting corrosion protection performance were also introduced. In the future，underwater self-healing，multi-channel defect response，in-situ marine validation experiments and industrial applications will be the important trends for thedevelopment of high-performance intelligent anti-corrosion coatings for marine environments.
