Abstract: 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.
