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.
