ACS Applied Materials & Interfaces, Journal Year: 2023, Volume and Issue: 15(26), P. 31720 - 31728

Published: June 25, 2023

Electromagnetic (EM) wave absorbers at a lower-frequency region (2–8 GHz) require higher attenuation ability to achieve efficient absorption. However, the impedance match condition and are usually inversely related. Herein, one-dimensional hollow carbon nanofibers with graphene nanorods prepared based on coaxial electrospinning technology. The morphology of can be controlled by annealing process. As time increased from 2 8 h, nanospheres grew into nanorods, which were catalyzed Co catalysts derived ZIF-67 nanoparticles. These play role nano-antennas, guide EM waves materials enhance conditions. result, possess larger area ability. minimum reflection loss reaches −57.1 dB thickness 4.6 mm, effective absorption bandwidth cover almost both S C bands (2.4–8 GHz). This work contributes meaningful perspective modulation microwave performance in range.

High-entropy MXenes, as a new emerging class of materials, possess diverse compositions, unexpected physicochemical characteristics and great potentials for electromagnetic (EM) wave absorption. Herein, two single-to-few-layer high-entropy (Mo_0.25Cr_0.25Ti_0.25V_0.25)₃C₂T_x (Mo_0.2Cr_0.2Nb_0.2Ti_0.2V_0.2)₄C₃T_x, were synthesized the first time. During exfoliation delamination processes, structural, morphological compositional evolutions analyzed, verifying successful formation two-dimensional MXene nanosheets. Investigations indicate that with filling content only 35 wt%, powders filled composites exhibit high-efficiency EM absorption performances.
