［Objective/Significance］ Aiming at the severe corrosion threat in the marine environment and the limitations of traditional anti-corrosion coatings，the technical core and bottlenecks of self-warning and self-healing intelligent anti-corrosion coatings were clarified to provide a reference for their research and development as well as engineering application.［Analysis/Discussion/Progress］Focusing on marine scenarios，this paper combs the research status and functional mechanisms of self-reporting，self-healing and multi-functional integrated intelligent anti-corrosion coatings，summarizes existing problems and proposes corresponding solutions. It clarifiesthat self-warning relies on fluorescent/color-developing materials，self-healing depends on carrier release/dynamic bonds，and multi-function is achieved through composite filler integration；meanwhile， it identifies bottlenecks such as weak anti-interference of signals and difficulty in balancing self-healing and weather resistance，as well as their corresponding solutions.［Conclusion/Prospect］ Intelligent anti-corrosion coatings are an inevitable trend for long-term corrosion protection of marineengineering，in the future，it is necessary to break through technologies such as multi-functionalsynergy and extreme environment adaptation to promote their engineering application.
