摘　　要：综述了通过引入可逆Diels-Alder键和可逆共价双硫键的热引发和利用紫外线、红外线的光引发实现本征型自修复聚氨酯(PU)材料的研究进展;探讨了本征自修复的修复机理,并对自修复PU材料的发展方向进行了展望。This article reviewed the research progress in the intrinsic self-repairing polyurethane materials prepared by the introduction of reversible Diels-Alder bonds, the thermal initiation of reversible covalent disulfide bonds and the photoinitiation of ultraviolet and infrared rays. The mechanism of intrinsic self-repair was also discussed, and the development direction of self-repairing polyurethane materials was prospected.
