摘　　要：自愈合材料的独特性能使其在生物医学工程、航空航天、智能材料等领域具有巨大潜力。近年来,在自愈合材料的研究和设计中,主要集中在外援型和本征型两大类,本征型自愈合弹性体材料通过材料内部动态可逆的化学键实现损伤自主修复,无需外部修复剂,成为智能高分子材料领域的研究热点。其核心设计基于可逆非共价键(如氢键、离子键、金属配位键等)或可逆共价键(如Diels-Alder反应、双硫键等)的动态网络构建。本文重点概述了本征型自愈合弹性材料的研究进展和最新研究成果,对可逆共价键、可逆非共价键等作用构筑弹性体的方法与机理进行阐述,并分析了本征型自修复材料面临的巨大挑战和未来发展前景,推动自修复材料在柔性电子、医疗器件和软体机器人等领域的实用化进程。The unique properties of self-healing materials hold great potential in the field of biomedical engineering,aerospace industry and smart materials.In recent years,there had been reports on the research status,advantages and disadvantages of two self-healing elastomer materials(external type and intrinsic type).Intrinsic self-healing elastomers,which achieve autonomous damage repair through dynamic reversible chemical bonds within the material without requiring external healing agents,have emerged as a research hotspot in the field of intelligent polymer materials.Their core design relies on the construction of dynamic networks based on reversible non-covalent bonds(e.g.,hydrogen bonds,ionic bonds,metal-ligand coordination)or reversible covalent bonds(e.g.,Diels-Alder reactions,disulfide bonds).The latest research results of intrinsic self-healing are introduced,and the design and mechanism of reversible covalent bond and non-covalent bond and preparation of elastomer were summarized and described.The great challenges faced by the intrinsic self-healing materials at present were analyzed,and their future applications were prospected,and expanding into multi-scenario applications to advance practical implementations in flexible electronics,biomedical devices,and soft robotics.
