MXene presents excellent electrical conductivity, abundant surface functional groups and wonderful film-forming performance, 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 mechanism of the porous structure formed by different preparation methods and the internal relationship between the “microstructure-macroscopic 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、丰富的表面官能团和良好的成膜性能，但层状层在成膜过程中容易发生自堆积，这会减少电磁波的损失，阻碍离子传输，并限制了有效负载。其他功能材料。多孔结构的构建可以有效解决MXene片材的自堆叠问题。本文综述了MXene多孔薄膜在电磁干扰(EMI)屏蔽、锂/钠离子电池、赝电容器和生物医学科学应用方面的研究进展。专注于MXene多孔薄膜的制备方法，并讨论了不同制备方法形成的多孔结构的成孔机理以及MXene多孔薄膜“微观结构-宏观性能”之间的内在联系，指出了该领域亟待解决的关键科技瓶颈。 MXene多孔薄膜的制备与应用 希望为MXene多孔薄膜的设计、制备、优化、工业应用和开发提供一定的指导。
