In this work, hierarchical architecture MoS2/CNT nanohybrids synthesized by the hydrothermal method, with different CNT proportions are systematically investigated for their microwave absorption. MoS2 nanoflowers are anchored uniformly on the surface of a CNT when the proportion of the MoS2/CNT nanohybrids was 10:2, and the reflection loss can attain -20 dB in the range of 3.4-13.9 GHz with multiple thicknesses from 1.5-5.0 mm, while an optimal consequence of -46 dB can be reached at 6.6 GHz at 2.9 mm. The excellent performance indicates that the MoS2/CNT = 10:2 nanohybrids have the potential for use as microwave absorbing materials.
