Abstract
Sandwich-like structure of the MoS2/TiO2/Ti3C2Tx nanocomposites were synthesized by a hydrothermal method. The corresponding phases, microstructure, and electromagnetic parameters were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and vector network analyzer. The results indicated that the Ti3C2Tx can be partially converted to TiO2 nanocrystals during the process of synthesized MoS2, the complex permittivity of MoS2/TiO2/Ti3C2Tx nanocomposite was increased after deposited MoS2, and therefore the electromagnetic and microwave absorbing performance was affected. When the thickness of MoS2/TiO2/Ti3C2Tx absorber was 2.5 mm, the corresponding absorption bandwidth (< −10 dB) was 2.6 GHz. The enhanced absorbing performance was attributed to the good impedance matching property, high attenuation constant and special sandwich-like structure.
