MXenes are two-dimensional (2D) transition metal carbides, nitrides, and carbonitrides with unique intrinsic properties, including excellent electrical conductivity, 2D sheet morphology, lightweight, flexibility, tunable surface chemistry, and easy solution processability, thus attracting considerable attention as electromagnetic interference (EMI) shielding materials. In this review, we demonstrate, from both experimental and theoretical perspectives, that the outstanding EMI shielding performance of MXenes is determined not only by its intrinsic properties but also by extrinsic modifications such as the introduction of dielectric inclusions, pores, or other designed structures. This review provides guidance for the efficient application of available resources, as well as insights into the challenges that should be addressed to develop more efficient and economical MXene based shielding materials for the advanced electronics industry of the future.

MXenes是具有独特固有特性的二维（2D）过渡金属碳化物，氮化物和碳氮化物，包括出色的导电性，2D片材形态，重量轻，柔韧性，可调的表面化学性质和易于加工的可加工性，因此作为电磁干扰吸引了相当多的关注（EMI）屏蔽材料。在这篇综述中，我们从实验和理论两个角度证明，MXene出色的EMI屏蔽性能不仅取决于其固有特性，还取决于外部修饰，例如引入介电内含物，孔或其他设计的结构。这项审查为有效利用可用资源提供了指导，
