摘　　要：聚氨酯材料因具有优异的综合性能而得到了广泛应用,但是其在使用过程中不可避免地会产生微裂纹等结构破坏,而自修复技术是解决这一问题的有效方案。本文阐述了非本征型和本征型自修复的机理,重点综述了本征型自修复材料的设计方法和研究进展,讨论了不同设计方法对材料自修复性能、力学性能等的影响,最后针对自修复材料自修复性能和力学性能的平衡问题,探讨了复合型自修复体系的可行性、设计思路和最新进展,提出了复合型自修复材料是今后的一大发展趋势,并展望了自修复材料面临的挑战和发展方向。Owing to their excellent comprehensive properties,polyurethane materials have been extensively used in commercial applications.However,such materials inevitably undergo structural damage such as microcracks during their service life.Recently,self-healing technology has been proposed as a feasible solution to this problem.Therefore,in this paper,the mechanisms of extrinsic and intrinsic self-healing materials are reviewed by focusing on the latest research progress and methods for designing intrinsic self-healing materials.The influences of different design methods on the self-healing and mechanical properties of the materials are discussed.Subsequently,aiming to address the difficulty in achieving a balance between self-healing and the mechanical properties of self-healing materials,composite self-healing materials have been proposed as a major development trend of the future,and therefore,the feasibility,design concepts,and latest research progress of such composite self-hea-ling systems are discussed and analyzed.Finally,current challenges and future development directions are summarized.
