The electromagnetic and microwave absorbing properties of MoS2 modified Ti(3)C(2)Tx nanocomposites

Sandwich-like structure of the MoS2/TiO2/Ti(3)C(2)Tx 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 Ti(3)C(2)Tx can be partially converted to TiO2 nanocrystals during the process of synthesized MoS2, the complex permittivity of MoS2/TiO2/Ti(3)C(2)Tx nanocomposite was increased after deposited MoS2, and therefore the electromagnetic and microwave absorbing performance was affected. When the thickness of MoS2/TiO2/Ti(3)C(2)Tx 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.
