“…The nanocomposites showed EMI SE values of 30–66 dB at thicknesses of ≈2–14 µm, resulting in ultrahigh SEE t values of 54 125 dB cm 2 g −1 . [ 152 ] These achievements were attributed to the synergy effect between the ultrafine cellulose and MXene, which generated abundant interfaces and allowed an excellent conduction and polarization losses.…”

The development of new materials for electromagnetic interference (EMI) shielding is an important area of research, as it allows for the creation of more effective and high‐efficient shielding solutions. In this sense, MXenes, a class of 2D transition metal carbides and nitrides have exhibited promising performances as EMI shielding materials. Electric conductivity, low density, and flexibility are some of the properties given by MXene materials, which make them very attractive in the field. Different processing techniques have been employed to produce MXene‐based materials with EMI shielding properties. This review summarizes processes and the role of key parameters like the content of fillers and thickness in the desired EMI shielding performance. It also discusses the determination of power coefficients in defining the EMI shielding mechanism and the concept of green shielding materials, as well as their influence on the real application of a produced material. The review concludes with a summary of current challenges and prospects in the production of MXene materials as EMI shields.

“…13,26 27 The introduction of organic polymers tends to increase the insulation gap among MXene nanosheets and reduce the EMI shielding properties in MXene-based composites. 28 In addition, most polymers are nonrenewable and have the disadvantage of being environmentally unfriendly. Therefore, using renewable and environmentally friendly materials such as cellulose nanofibers (CNFs) to composite with MXene to improve its mechanical properties has broad research prospects.…”

“…Therefore, CNC with lower density is more helpful in reducing the insulation gap among MXene nanosheets to progress the mechanical performance of composite materials. 28,35 However, further increasing the mechanical performance of the material may result in a loss of the EMI shielding property. Accordingly, it is necessary to introduce another highly conductive material, while enhancing the mechanical performance of the material.…”

With the increasing popularity of electronic communication equipment, electromagnetic pollution continues to worsen, and the requirement for ultrathin, highly flexible, and multifunctional electromagnetic interference (EMI) shielding films is becoming more imperative. Within this study, composite films were prepared by introducing one-dimensional (1D) cellulose nanocrystals (CNC) and silver nanowires (AgNWs) into twodimensional (2D) MXene-based materials using the method of vacuum-filtration-induced self-assembly. Benefiting from the 1D/ 2D conductive network composed of AgNWs and MXene, the composite film has a high conductivity (36,244 S m −1 ) and excellent EMI shielding performance (69.94 dB) at a thickness of 54 μm. The introduction of a 1D sustainable CNC as a "binder" increased the tensile strength of the composite film from 16.75 MPa (pure Ti 3 C 2 T x MXene film) to 26.14 MPa. In addition, the MXene/AgNWs/CNC composite films have outstanding Joule heating performance, and the surface temperature exceeded 70.2 °C under 2.5 V. Moreover, the MXene/AgNWs/CNC composite films have recyclable properties, and the test results indicate that the EMI SE value of the composite films is 40.78 dB after recycling. We believe that the designed MXene/AgNWs/CNC composite films have promising applications with respect to electromagnetic protection in flexible wearable devices, aerospace systems, and extreme environments.
