Abstract

In this study, MoS2/Mn-Zn ferrite composites were obtained by mixing MoS2 and Mn-Zn ferrite via high-speed vibrating ball milling. The dielectric properties, magnetic properties and microwave absorption performance of MoS2, Mn-Zn ferrite and their composites were investigated in the frequency of 2-18 GHz. Then the mechanism of electromagnetic loss was further explored. Our results show that the imaginary permittivity (ε'') and imaginary permeability (μ'') of MoS2/Mn-Zn ferrite composites are between those of their parents, indicating that the composites have both dielectric and magnetic loss. The absorption capability of the composites is better than that of MoS2 at low frequency, and at high frequency, it is better than that of Mn-Zn ferrite. Compared with their parents, the composites have thinner matching thicknesses and broader effective bandwidths without obviously affecting the minimum reflection loss (RL) (still between −50 dB to −60 dB). The broadest effective bandwidth is 3.43 GHz of MS-DMR40-2-1, and the thinnest matching thickness is 1.59 mm of MS-DMR40-1-2. The enhanced microwave absorption performances of MoS2/Mn-Zn ferrite composites are mainly attributed to the improved impedance matching and dual-loss mechanism. We believe that MoS2/Mn-Zn ferrite composites are promising for the potential applications as novel, efficient microwave absorbents.
