Abstract：With the rapid development of wireless communication technology,electromagnetic pollution is continuously intensifying.Therefore,it is of great significance to study composite absorbing materials with excellent performance.Molybdenum disulfide(MoS2),with its two-dimensional nanolayered struc-ture and large specific surface area,is a dielectric loss material;while triiron tetroxide(Fe3O4)exhibits magnetic loss.The combination of these two results in superior absorbing performance.In this study,so-dium molybdate and thioacetamide were used as molybdenum and sulfur sources,respectively,and ferric chloride and ferrous sulfate were served as iron sources.MoS2@Fe3O4 composite materials were prepared using either one-step or stepwise hydrothermal methods.The effects of different hydrothermal pathways on the phase structure,microstructure,and absorbing performance of the products were investigated.The results demonstrated that the absorbing performance of MoS2@Fe3O4 composite materials prepared by different hydrothermal pathways varied significantly.When the thickness was 2.8 mm,the minimum reflection loss of MoS2@Fe3O4 composites prepared by one-step and stepwise hydrothermal methods was-39.72 and-43.18 dB,respectively;the effective absorption bandwidths were 7.28 and 2.08 GHz,respectively.
