Construction of core-shell structured SiO2@MoS2 nanospheres for broadband electromagnetic wave absorption

Xuewen Jiang et al.

Summary: Core-shell structured SiO2@MoS2 nanospheres were prepared via hydrothermal method, with MoS2 nano-sheets irregularly growing on the outside surface of SiO2. The microstructure and EM wave absorption properties of SiO2@MoS2 nanospheres were explored. SiO2@MoS2 achieved a minimum reflection loss (RLmin) value of -49.35 dB with a thickness of 2.8 mm, and an effective absorption bandwidth (EAB) of 7.44 GHz. The remarkable EM wave absorption performance could be attributed to the interfacial polarization from the core-shell structure and multiple reflections on MoS2 ultrathin nanosheets, as well as the effective impedance matching provided by the combination of SiO2 and MoS2.
