Abstract
Reduced graphene oxide-molybdenum disulfide (RGO-MoS2) loaded Fe3O4 nanoparticles composite (RGO-MoS2-Fe3O4) is prepared via two-step hydrothermal reaction. RGO-MoS2 possesses three dimension architecture structures. This structure can prevent RGO and MoS2 nanosheets restacked together and provide substrates for the Fe3O4 nanoparticle decoration. The sizes of Fe3O4 are in the range of 5–20 nm. As a microwave absorbent: the minimum reflection loss (RL) value is -47.67 dB at 17.44 GHz when the thickness is only 1.5 mm. The absorption bandwidth (RL < −10 dB) can reach 4.72 GHz with the thickness is 1.7 mm. Compared with the previously reported literature, RGO-MoS2-Fe3O4 nanocomposite exhibits excellent microwave absorption performance and can be served as an light-weight microwave absorber.
