MXene has excellent electrical conductivity, abundant surface functional groups and wonderful film-forming properties, but the lamellar layers are prone to self-stacking during film formation, which will reduce the loss of electromagnetic waves, hinder ion transmission, and limit the effective load of other functional materials. The construction of the porous structure can effectively solve the self-stacking problem of MXene sheets. This article reviews the research progress of MXene porous films for electromagnetic interference (EMI) shielding, lithium/sodium ion batteries, pseudocapacitors, and biomedical science applications. It focuses on the preparation methods of MXene porous films, and discusses the pore-forming mechanisms of the porous structure formed by different preparation methods and the internal relationship between the "microstructure-macro performance" of the MXene porous films, points out the key scientific and technical bottlenecks that need to be solved urgently in the preparation and application of the MXene porous films. It is hoped to provide certain guidance for the design, preparation, optimization, industrial application and development of MXene porous films.

MXene具有优异的导电性、丰富的表面官能团以及极佳的成膜性，但成膜时片层极易发生自堆叠，会降低其对电磁波的损耗、阻碍离子传输，还会限制其它功能材料的有效负载。多孔结构的构建可以有效解决MXene片层的自堆叠问题。本文综述了电磁干扰（EMI）屏蔽、锂/钠离子电池、赝电容器和生物医用领域用MXene多孔膜的研究进展，着重介绍了MXene多孔膜的制备方法，探讨了不同制备方法形成多孔结构的成孔机理以及MXene多孔膜“微观结构-宏观性能”的内在关系，指出了MXene多孔膜在制备以及应用过程中亟待解决的关键科学和技术瓶颈问题，希冀能为MXene多孔膜的设计制备优化、工业化应用及发展提供一定的指导。
