This review encompasses the research progress on self‐healing properties of epoxy polymers and is divided into two categories: material supplement and energy supplement. The central concept of material supplement revolves around the addition of functional composite materials, such as, hollow fiber and microcapsule, to repair the micro‐cracks of epoxy polymers. In contrast, the energy supplement is based on the concurrent incorporation of some functional groups into the thermosetting epoxy polymers. These functional chemical groups participate in the construction of a three‐dimensional network structure of thermosetting materials and successfully enter the block copolymer of epoxy polymers. When the micro‐cracks are developed in the resin upon exterior impact, these functional groups automatically absorb energy from the outside to perform chemical reactions and automatically repair their micro‐cracks following the self‐healing phenomenon. Five kinds of reversible reactions are introduced for energy supply and are discussed in detail. Finally, a summary and comparison of the self‐healing methods covered in this review and the application prospect of self‐healing epoxy polymers are summarized.

环氧聚合物的自愈能力综述
这篇综述涵盖了环氧聚合物自愈性能的研究进展，分为两大类：材料补充剂和能量补充剂。材料补充剂的中心概念围绕添加功能性复合材料（例如中空纤维和微胶囊）来修复环氧聚合物的微裂纹。相反，能量补充剂基于同时将一些官能团结合到热固性环氧聚合物中。这些功能性化学基团参与热固性材料的三维网络结构的构建，并成功进入环氧聚合物的嵌段共聚物。当外部冲击在树脂中产生微裂纹时，这些官能团会自动从外部吸收能量以进行化学反应，并在自愈现象发生后自动修复微裂纹。引入了五种可逆反应进行能量供应，并进行了详细讨论。最后，总结和比较了本文中涉及的自修复方法以及自修复环氧聚合物的应用前景。
