“…[4] However, the pristine Ti 3 C 2 T x possesses high electrical conductivity (higher than 10 000 S cm −1 ), leading to impedance mismatch and showing EM interference (EMI) shielding performance. [5] For instance, Ti 3 C 2 T x foam with a density of 5.5 mg cm −3 shows shielding effectiveness of 54.8 dB. [6] To optimize the impedance match condition, heterogeneous interface design based on Ti 3 C 2 T x has been carried out, such as Ti 3 C 2 T x /SiC, Ti 3 C 2 T x /NiCo 2 O 4, and so on.…”

Heterogeneous interface design to boost interfacial polarization has become a feasible way to realize high electromagnetic wave absorbing (EMA) performance of dielectric materials. However, interfacial polarization in simple structures such as particles, rods, and flakes is weak and usually plays a secondary role. In order to enhance the interfacial polarization and simultaneously reduce the electronic conductivity to avoid reflection of electromagnetic wave, a more rational geometric structure for dielectric materials is desired. Herein, a Ti 3 C 2 T x /MoS 2 self-rolling rod-based foam is proposed to realize excellent interfacial polarization and achieve high EMA performance at ultralow density. Different surface tensions of Ti 3 C 2 T x and ammonium tetrathiomolybdate are utilized to induce the self-rolling of Ti 3 C 2 T x sheets. The rods with a high aspect ratio not only remarkably improve the polarization loss but also are beneficial to the construction of Ti 3 C 2 T x /MoS 2 foam, leading to enhanced EMA capability. As a result, the effective absorption bandwidth of Ti 3 C 2 T x /MoS 2 foam covers the whole X band (8.2-12.4 GHz) with a density of only 0.009 g cm −3 , at a thickness of 3.3 mm. The advantages of rod structures are verified through simulations in the CST microwave studio. This work inspires the rational geometric design of micro/nanostructures for new-generation EMA materials.

“…A solution processed Ti 3 C 2 T x MXene microstrip transmission line was recently reported to enable low-energy attenuation and patch antennas with high-power radiation at frequencies from 5.6 to 16.4 GHz. 322 The radiation efficiency of a 5.5 mm thick MXene patch antenna manufactured reached 99% at 16.4 GHz, which is about the same as that of a standard 35 mm thick copper patch antenna at about 15% of its thickness and 7% of the copper weight. Moreover, in another study, a reliable excellent Schottky junction and an ohmic contact to WSe 2 were successfully achieved using conventional device fabrication processes compatible with semiconductor industry.…”

There is an urgent global need for wireless communication utilizing materials that can provide simultaneous flexibility and high conductivity. Avoiding the harmful effects of electromagnetic (EM) radiation from wireless communication is a persistent research hot spot. Two-dimensional (2D) materials are the preferred choice as wireless communication and EM attenuation materials as they are lightweight with high aspect ratios and possess distinguished electronic properties. MXenes, as a novel family of 2D materials, have shown excellent properties in various fields, owing to their excellent electrical conductivity, mechanical stability, high flexibility, and ease of processability. To date, research on the utility of MXenes for wireless communication has been actively pursued. Moreover, MXenes have become the leading materials for EM attenuation. Herein, we systematically review the recent advances in MXene-based materials with different structural designs for wireless communication, electromagnetic interference (EMI) shielding, and EM wave absorption. The relationship governing the structural design and the effectiveness for wireless communication, EMI shielding, and EM wave absorption is clearly revealed. Furthermore, our review mainly focuses on future challenges and guidelines for designing MXene-based materials for industrial application and foundational research.
