Inspired by the self-healing function of living organisms, self-healing materials have been developed in recent decades to very high standards. As a new direction, self-healing fibrous membranes (SFMs) exhibit both the configuration of a porous structure and self-healing capability within one material. Different from nonporous self-healing materials, it is more challenging to introduce self-healing properties to porous fibrous membrane materials owing to the more complex healing mechanism and microstructure of SFMs. This Minireview focuses on the self-healing mechanisms, design principles, and preparation strategies of SFMs. The characteristics of SFM self-healing performance are introduced in detail, and insights and perspectives of SFM preparation and healing mechanisms are put forward. Furthermore, remaining challenges and future developments of SFMs are presented, where the ultimate goal is the design of highly efficient self-healing and superstable fibrous membranes.
受生物体自愈功能的启发，近几十年来，人们已经将自愈材料的开发提升到了一个很高的标准。作为一个新的方向，自愈合纤维膜（SFMs）在一种材料中同时具有多孔结构的配置和自愈合能力。与非多孔自愈材料不同，由于 SFMs 的愈合机制和微观结构更为复杂，将自愈性能引入多孔纤维膜材料更具挑战性。这篇综述聚焦于 SFMs 的自愈合机制、设计原则和制备策略。详细介绍了 SFMs 自愈合性能的特点，并提出了对 SFMs 制备和愈合机制的见解和展望。此外，还介绍了 SFMs 目前存在的挑战和未来的发展方向，最终目标是设计高效的自愈和超稳定的纤维膜。
