Microwave absorption performance of sandwich-like Ti3C2Tx@BFO composite material in C and X bands

In this study, the sandwich-like Ti3C2Tx@BFO were synthesized by a hydrothermal method. The structural, surface morphology, chemical composition and magnetic properties of studied materials were characterized by XRD, SEM, FTIR and VSM. The complex permittivity and permeability of the materials were characterized by VNA to study their microwave absorption characteristics. Results revealed that dielectric loss of Ti3C2Tx@BFO composites can be enhance due to the introduction of Ti3C2Tx MXene, which cause improved matching impedance, effective bandwidth and microwave absorption performance of Ti3C2Tx@BFO. It was found that when the Ti3C2Tx MXene mass fraction is as low as 5%, the RLmin can reach-57.95 dB with the thickness is 2.97 mm, and the effective absorption bandwidth maximum is 4.84 GHz with the matching thickness is 2.4 mm. The Ti3C2Tx@BFO has received widespread attention due to its low preparation cost and high absorption performance. We trust that Ti3C2Tx@BFO is a promising microwave absorbing material.
