Abstract: The research status of self-healing polymer was reviewed. Self-healing method in polymer materials includes extrinsic self-healing（nanoparticles self-healing，microcapsules self-healing，hollow-fibers self-healing and microvessels self-healing，et al） and intrinsic self-healing（reversible covalent bond self-healing，reversible non-covalent bond self-healing）. Research progress in intrinsic self-healing polymer materials in recent years is summarized. Reversible covalent bond self-healing method realized the function with the help acylhydrazone bond，disulfide-bond，N—O bond and Dieal-Alder reaction in polymer system. Reversible non-covalent bond self-healing method depend on the interaction of hydrogen bond，hydrophobically，static electricity，ionomers，molecular diffusion and metal-ligand. Intrinsic self-healing mechanisms and present research status were elaborated. The potential application fields of smart self-healing materials such as high-rise buildings，nuclear material storage and biology medical material are prospected.

Key words: intrinsic self-healing, polymer materials, self-healing mechanisms

摘要： 回顾了自修复聚合物材料的研究现状，目前所采用的自修复方法主要包括外援型自修复（纳米粒子自修复、微胶囊自修复、空心纤维自身修复、微脉管自修复等）和本征型自修复（可逆共价键自修复、可逆非共价键自修复），重点介绍了本征型自修复聚合物材料的最新研究进展，可逆共价键自修复是通过在体系中引入酰腙键、双硫键、N—O键、Dieal-Alder可逆反应等实现的，可逆非共价键自修复是借助于体系中的氢键作用、疏水作用、静电作用、离子作用、大分子扩散作用、金属配体作用等机理实现的，对它们的修复机理及研究现状进行了系统的阐述，展望了自修复材料潜在的应用领域，如高屋建筑、核材料贮存、生物医疗材料等。
