“…Therefore, the development of catalyst-free, self-healing core materials can expand the range of applications for self-healing materials and avoid the effects of catalyst failure. One-component self-healing systems without the aid of catalysts and curing agents, represented by dry oils, [29][30][31] isocyanates, [32][33][34] and active silicones, [35][36][37] have been rapidly developed. The molecular structure of the repair agent of this system usually contains active functional groups that can polymerize under the action of O 2 , H 2 O, or light to realize the repair of coating defects and show good self-repair and corrosion resistance.…”
