Abstract
High-performance electromagnetic wave absorption materials with strong absorption intensity, broad bandwidth, low density and thin thickness can be widely applied in the civil and military areas. In this paper, FeNi3 nanoalloy decorated on 3D architecture composite of reduced graphene oxide/molybdenum disulfide (FeNi3@RGO/MoS2) was prepared by two-step of hydrothermal reaction. RGO/MoS2 composite was synthesized by a hydrothermal process and then FeNi3 nanoalloy was decorated on the RGO/MoS2 nanosheets via the second hydrothermal process. Electromagnetic wave absorption performances of FeNi3@RGO/MoS2 composite with different filler loadings in paraffin matrix were investigated for the first time and it improves significantly with the increase of filler loading. The maximum absorption bandwidth is 4.72 GHz with the thickness of 2.0 mm and the corresponding reflection loss value is −30.39 dB when the filler loading of FeNi3@RGO/MoS2 is 40%. The ternary composite possesses dielectric loss and magnetic loss in the testing frequency region, magnetic loss plays an important role in low-frequency region and dielectric loss occupies the main part in the high-frequency area.
