Abstract: In this paper, research progress of Intrinsic self-healing coatings based on photochemical reaction were introduced, with emphasis on the UV-cured self-healing coatings based on disulfide bond exchange, Diels-Alder reversible reactions, hydrogen bonds, photo-crosslinking reaction and self-replenishing action. The preparation method, self-healing mechanism and repair efficiency of the coatings were described. Moreover, the future development and application of the Intrinsic self-healing coatings based on photochemical reaction were forecasted.

Key words: coatings, intrinsic, self-healing, dynamic reversible chemistry
