“…This produces a dielectric-magnetic synergistic effect that increases the impedance and enhances attenuation. 19 As a consequence, several investigators have zeroed in on designing multidimensional, multielement microwave-absorbing materials using MXene, graphene, and magnetic loss materials. Cui et al, for instance, manufactured rGO/MXene/Fe 3 O 4 microspheres via the ultrasonic spray technique; the RL min was −51.2 dB at 11.1 GHz and the EAB was 4.7 GHz with a thickness of just 2.9 mm.…”

Efficient electromagnetic wave absorption (EMA) materials are urgently needed to solve the increasingly serious electromagnetic pollution problems in both the modern military and civil fields. Multidimensional and multielement electromagnetic absorbing materials exhibit enormous potential in EMA applications owing to the combination of material and structure advantages. Herein, a three-dimensional (3D) reduced graphene oxide/Ti 3 C 2 T x MXene/iron−cobalt alloy carbon (rGO/MXene/FeCoC) nanocomposite aerogel derived from FeCo-ZIF metal−organic frameworks (MOFs) was successfully fabricated by combining freezedrying and pyrolysis methods. The minimum reflection loss (RL min ) of the optimized rGO/MXene/FeCoC-30% is −61.4 dB and the effective absorption band (EAB, <−10 dB) reaches up to 4.95 GHz with a matching thickness of 1.55 mm. The outstanding EMA performance benefits the excellent impedance matching, the rich multiple reflections and scattering in three-dimensional porous structures, and the favorable dielectric-magnetic synergistic losses endowed by graphene, MXene, and FeCoC nanoparticles. The successful construction of the multicomponent rGO/MXene/FeCoC nanocomposite aerogel provides a prospective direction for the development of high-efficient electromagnetic absorbing materials.

Thin‐thickness and light‐weight electromagnetic wave (EMW) absorption materials are critically needed for stealth technology in the military stealth field. The special structure of a material is important for improving its good EMW absorption. In this work, a series of porous MOF‐derived LaCo/C decorated Ti 3 C 2 T x (LaCo/C/Ti 3 C 2 T x ) composites were prepared by carbonization at high temperatures. Impressively, the minimum reflection loss (RLmin) of LaCo/C/Ti 3 C 2 T x ‐2 is ‐47.72 dB at 10.26 GHz (thickness 2.3 mm), and the optimal effective absorption bandwidth is 5.45 GHz (thickness 1.9 mm). The excellent EMW absorption properties are due to multiple electromagnetic loss mechanisms, such as polarization loss, magnetic loss, and multiple reflections and scattering. This work provides a new route for the application of Ti 3 C 2 T x ‐based derivatives.This article is protected by copyright. All rights reserved.
