ABSTRACT Ion gels, soft materials that contain ionic liquids (ILs), are promising gel electrolytes for use in electrochemical devices. Due to the recent surge in demand for flexible and wearable devices, highly durable ion gels have attracted significant amounts of attention. In this review, we address recent advances in the development of ion gels that can heal themselves when mechanically damaged. Light- and thermally induced healing of ion gels are discussed as stimuli-responsive healing strategies, after which self-healable ion gels based on supramolecular and dynamic covalent chemistry are addressed. Tough, highly stretchable, and self-healable ion gels have recently been fabricated through the judicious design of polymer nanostructures in ILs in which polymer chains and IL cations and anions interact. The applications of self-healable ion gels to electrochemical devices are also briefly discussed.

自修复离子凝胶的最新进展

摘要 离子凝胶是一种含有离子液体 (IL) 的软材料，是用于电化学装置的有前途的凝胶电解质。由于最近对柔性和可穿戴设备的需求激增，高度耐用的离子凝胶引起了大量关注。在这篇综述中，我们讨论了离子凝胶开发的最新进展，这些离子凝胶在受到机械损坏时可以自我修复。离子凝胶的光和热诱导愈合被讨论为刺激响应性愈合策略，之后基于超分子和动态共价化学的自修复离子凝胶得到解决。最近通过 IL 中聚合物纳米结构的明智设计制造了坚韧、高度可拉伸和自愈的离子凝胶，其中聚合物链和 IL 阳离子和阴离子相互作用。
