“…Yan et al developed a “sandwich” structured MXene/aramid nanofiber (ANF)/carbon nanotube (CNT) aerogel . Due to the one-dimensional nanostructure of carbon nanotubes and the two-dimensional layered structure of MXene, these structures can increase the scattering and multiple reflections of electromagnetic waves within the material, extending the propagation path of the electromagnetic waves and improving the absorption efficiency. , Therefore, carbon nanotubes and MXene contribute to the absorption and reflection of electromagnetic waves . Although the thickness and density of the composite aerogel are only 2 mm and 0.0428 g·cm –3 , respectively, the electromagnetic shielding effectiveness in the X-band reached 69.0 dB.…”

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.

To cope with the increasingly serious electromagnetic pollution, the demand for electromagnetic interference (EMI) shielding materials with low electromagnetic wave reflection ability has become urgent. Controlling electrical components, magnetic components, and designing the EMI material structure can effectively improve electromagnetic shielding performance, but this remains a significant challenge. Besides, extreme cold weather conditions also do considerable potential damage to the normal work of outdoor electronic equipment. Integrated light‐to‐heat conversion capability on electromagnetic shielding materials can further improve the stability and reliability of the equipment. Herein, the novel bilayer aerogels composed of zeolitic imidazolate frameworks derived hollow CoNi carbon nanocage/MXene Ti3C2Tx/nanocellulose (BZMN) are prepared by a two‐step freezing method. BZMN aerogels exhibit good EMI shielding effectiveness (SE) with low reflection coefficient (R coefficients): 35.1 dB (R coefficient = 0.28) and 21.2 dB (R coefficient = 0.25). The unique structures of bilayer aerogels demonstrate the ability to absorb more electromagnetic waves through interfacial polarization and multiple scattering. The green shielding index (gs) of BZMN aerogels can reach 2.88. Moreover, BZMN aerogels show remarkable and unique light‐to‐heat conversion performance on different surfaces. Under 2.0 sun intensity, temperatures can reach 109.3 °C in the upper layer and 102.3 °C in the lower layer. Under 0.8 W cm−2 near‐infrared (NIR) laser intensity, the temperatures can rise to 234.1 °C in the upper layer and 167.4 °C in the lower layer. In addition, the size and shape of BZMN aerogels can be customized according to the mold. These features present BZMN aerogels as advanced potential low reflection EMI shielding device candidates, useful for future telecommunication and electronic equipment protection.

Anchoring magnetic ZIF-67 on Ti₃C₂T_x MXene to form composite films with high electromagnetic interference shielding performance

Abstract: The MXene@ZIF-67/MWCNTs composite films are successfully prepared by anchoring ZIF-67 on MXene in combination with MWCNTs in a simple vacuum-assisted filtration, and provide a high EMI SE of 63.6 dB while achieving high absorption loss and good thermal conductivity.
