Abstract
MXene/CoS heterostructures were synthesized by using an electrostatic self-assembly strategy, as an electromagnetic wave (EMW) absorber to deal with EMW pollution. MXene (Ti3C2Tx) layered-structure was naturally obtained by using the typical etching method. Modified CoS hollow microspheres were deposited on the surface MXene through layer by layer electrostatic interaction. Eventually, the heterostructures exhibited significantly enhanced EMW absorption performance owing to the synergistic effect of multiple loss mechanisms. Furthermore, EMW absorption performance can be optimized by simply adjusting the mass ratio of Ti3C2Tx to CoS. Specifically, the minimum reflection loss (RLmin) was ?60.28 dB at 12.24 GHz, with an effective absorption bandwidth of 3.04 GHz, at the thickness of 1.81 mm. Accordingly, it is reasonable to believe that this structural design strategy offers a new direction for the next-generation of EMW absorbers.
