摘　　要：固–固相变材料以其优异的热储存能力及热循环稳定性而得到广泛应用,但在加工和使用过程中经常受到外部刺激而造成破损,降低使用寿命甚至产生安全隐患。结合固–固相变材料的研究与使用中出现的问题,许多研究人员尝试将自修复概念引入固–固相变材料中,赋予相变材料自我诊断及修复功能,延长相变材料的使用寿命。本文回顾了固–固相变材料的制备方法,介绍了自修复技术的主要机理,整理了当前不同自修复机理构筑可自修复性固–固相变材料的相关研究进展,并对可修复性固–固相变材料的进一步研究提出了展望。Solid-Solid Phase Change Materials (SSPCMs) have been widely applied because of their excellent heat storage capacity and thermal cycle stabil-ity. However, they are often damaged by external stimuli during processing and use, reducing ser-vice life and even causing safety hazards. In combination with the problems in the research and use of Solid-Solid Phase Change Materials, many researchers have tried to introduce the concept of self-repair into Solid-Solid Phase Change Materials, endow the materials with self-diagnosis and re-pair functions, and extend the service life of phase change materials. In this paper, the preparation methods of Solid-Solid Phase Change Materials are reviewed, the main mechanisms of self-healing technology are introduced, and the relevant research progress of constructing self-healing retracta-ble Solid-Solid Phase Change Materials with different self-healing mechanisms is summarized. Meanwhile, future research prospects of repairable Solid-Solid Phase Change Materials are pro-posed.
