Abstract
Ti3C2Tx MXene exhibits great potential application in the microwave absorption (MA) field mainly due to its two-dimensional (2D) characteristic and high dielectric loss. However, their wide application is limited by the inferior properties of without magnetic loss and narrow bandwidth in microwave frequency range. Driven by the further demands of MA performance improvement, sandwich-like CoFe@Ti3C2Tx composites are designed and successfully fabricated by in-situ reduction in the presence of hydrazine, and the minimum reflection loss (RL) value of −36.29 dB at 8.56 GHz could be achieved with the thickness of 2.2 mm. The enhanced microwave absorption of CoFe@Ti3C2Tx composites should originate from the unique sandwich-like structure, good impedance matching characteristic, and enhanced interfacial polarization. In addition, the coating made by CoFe@Ti3C2Tx composites located on the substrates of aluminum plate and fabric exhibited good heat dissipation capability, which was studied through thermal infrared images. This work provides a new avenue for exploring high-performance microwave absorbers of MXene-based magnetic materials.
