MXene emerges as a premier candidate for electromagnetic shielding owing to its unique properties as a novel two-dimensional material. Its exceptional electrical conductivity, chemical reactivity, surface tunability, and facile processing render it highly suitable for diverse electromagnetic shielding applications. The research status of MXene and MXene-based electromagnetic shielding materials is systematically discussed in this paper. First, the research status of MXene as a single-component electromagnetic shielding material is briefly introduced. Subsequently, the research status of composite structures constructed by MXene with polymers, carbon derivatives, and ferrites is introduced in detail. Furthermore, the research progress of MXene-based ternary and quaternary composite electromagnetic shielding materials is further focused. Finally, the application of MXene-based composite electromagnetic shielding materials is prospected. A deeper understanding of MXene’s electromagnetic shielding properties is facilitated by this paper, providing the direction for the future development of two-dimensional materials in the design and processing of electromagnetic shielding materials.

The development of electronic fuze has placed higher demands on encapsulation resins, which are required to provide not only insulation and protection, but also higher impact resistance and good electromagnetic shielding performance. A new composite material consisting of hollow glass microspheres (HGM) and modified epoxy resin was developed. This material exhibits significant electromagnetic shielding capabilities for terahertz (THz) waves, as well as superior impact energy absorption properties. Bisphenol A‐type epoxy resin (E‐44) was modified using Al(OH)3, red phosphorus, carbon black, and SiO2, and the material properties were optimized by adjusting the HGM content. The electromagnetic shielding effectiveness and impact energy absorption of the composite material in the THz band were comprehensively tested using THz time‐domain spectroscopy and split Hopkinson pressure bar testing systems. Additionally, a comprehensive evaluation of the mechanical and dielectric properties, thermal conductivity, and thermal stability of the material was conducted. The results showed that the electromagnetic shielding effect of 60 vol.% HGM hybrid‐modified resins was the best, reaching 43.78 dB. The 20 vol.% HGM hybrid‐modified resins not only has a specific absorption energy of 18.51 J/cm3, but also has the best overall performance. This work has advanced the design and development of multifunctional and impact‐resistant potting epoxy resins.

Functionalized thin films with excellent flexibility and conductivity can meet the current requirements for electromagnetic(EM) shielding materials. In this paper, 2D transitions metal carbide and nitride nanomaterials Ti3C2Tx MXene were prepared by chemical exfoliation, and PVDF/MWCNTs/3 wt%/RGO@Fe3O4@ AgNWs‐10 based on PVDF/MWCNTs‐3 wt%/RGO@Fe3O4@AgNWs‐10, The samples were prepared through a simple solution mixing process followed by vacuum‐assisted filtration (VAF), and PVDF/MWCNTs/MXene/RGO@Fe3O4@AgNWs three‐layer PVDF‐based composite films, which were analyzed for electrical conductivity and EM shielding properties, which increased and then decreased with the rise in the Ti3C2Tx MXene content, in which the highest electrical conductivity of the three‐layer composite films of M3/MX‐10/R@F@Ag was obtained when the Ti3C2Tx MXene addition amount reached 10 mL as 3.9 × 103 S/m, the EMI SET is 54.9 dB, the EMI SEA is 44.8 dB, the absorption loss is 81.6%, and the SSEt of the M3/MX‐10/R@F@Ag three‐layer composite film is the highest 1672.5 dB/(cm−2·g). And the SEA/SER ratios of the M3/MX‐X/R@F@Ag three‐layer composite films are all greater than 1. The result shows that the EM attenuation mechanism of the M3/MX‐X/R@F@Ag three‐layer composite films is primarily driven by absorption loss and that the incorporation of Ti3C2Tx Mxene improves the EM shielding performance of the composite films. The relatively novel exploration of the performance study and structural design of the M3/MX‐X/R@F@Ag three‐layer EM shielding composite film provides structural design and research ideas for the application of the new MXenes material in EM shielding composites.Highlights The addition of Ti3C2Tx MXene will generate more conductive network nodules A complete 3D conductive network is constructed in the membrane This paper discusses the influence of Ti3C2Tx MXene on EM shielding Multiple internal reflections of EMW between Ti3C2Tx MXene 2D nanosheets The EM shielding mechanism of the film is discussed from the angle of 3D
