Abstract
Presently, electromagnetic wave absorbing materials are rapidly developing towards the direction with thin, light, wide, and strong characteristics. Based on this target, the like-hydrangea Fe3O4@MoS2 composites were synthesized using facile hydrothermal technology. In this work, the effect of molar ratio between MoS2 and Fe3O4 as well as micro-morphology on electromagnetic wave absorption properties was discussed emphatically. As a result, when the molar ratio was 1:2 and match thickness of sample was 2.5 mm, the minimum reflection loss (RLmin) achieved −96.77 dB at 10.64 GHz. At the same time, the effective absorption bandwidth (EAB) was 10 GHz ranging from 7.6 to 17.6 GHz. In final, the microwave absorption mechanisms of like-hydrangea Fe3O4@MoS2 composites were proposed.
