Abstract

An electrostatic self-assembly method is used to synthesize FeSiCr/MXene, and the effect of MXene on the wave-absorbing properties is studied in this paper. The electromagnetic parameters of the composites are adjusted by optimizing the amount of MXene to improve the dielectric polarization and achieving impedance matching in order to enhance the microwave-absorbing properties. The lowest reflection loss (RL_min) of FeSiCr/MXene composites is −50.34 dB at 13.75 GHz. When the quantity of MXene composite is 15 wt % and the matching thickness is only 1.32 mm, the effective absorption bandwidth (EAB) at 2.00 mm approaches 11.05 GHz. The improved FeSiCr impedance matching, together with synergistic effects such as dielectric loss and interfacial polarization, results in outstanding microwave absorption performance for the FeSiCr/MXene composites. This paper proposes a new approach to developing and synthesizing materials with lightweight and efficient electromagnetic wave absorption.
