چکیده انگلیسی
Molybdenum disulfide (MoS2), as a significant microwave absorption materials, has been widely reported. However, it is unclear and insufficient about its microwave absorption mechanism. In this work, a series of MoS2-based materials with different morphology, including MoS2 nanosheets (MoS2-NS), hierarchical MoS2 (H-MoS2) microspheres, hollow hierarchical MoS2 (HH-MoS2) microspheres and hydrangea-like MoS2/C (MoS2/C) microspheres, were synthesized via hydrothermal reaction. More importantly, the microwave absorption mechanism and the dielectric properties as well as microwave absorption performance (MAP) were systemically studied. The results indicated that MoS2/C exhibited eminent dielectric properties and MAP, which resulted from the unique structure and component. The minimum reflection loss (RL) value of MoS2/C microspheres/wax with 30â¯wt% loading is â44.67â¯dBâ¯at the thickness of 1.4â¯mm, and the corresponding bandwidth with effective attenuation (RLâ¯<â¯-10â¯dB) is up to 3.32â¯GHz (11.7-15.02â¯GHz).
