Abstract: In the field of anti-corrosion, epoxy resin anti-corrosion composite coating is an excellent material to prevent metal corrosion. The epoxy coating forms a barrier between the metal and the corrosive ions, but the anti-corrosion effect of the epoxy resin does not last long during curing due to mechanical breakage and the formation of micropores. Three strategies for enhancing the anticorrosive properties of epoxy resin are introduced in this paper, namely nanoparticle modification, micro/nano container modification, and bio-based material modification. The research progress of epoxy resin anticorrosive composite coating modification is reviewed, and the future development direction of epoxy resin anticorrosive composite coating is prospected. In the future, a green epoxy anticorrosive composite coating with intelligent self-warning and self-repair, multi-function and cost-effective should be developed.
