Synthesis of Silanized MoS2/Reduced Graphene Oxide for Strong Radar Wave Absorption

Special materials for radar wave absorption (RWA) and stealth camouflage techniques are desired, because of their wide-spread applications in the military field. In this paper, silanized MoS2 (M/MoS2)/reduced graphene oxide (rGO) nanosheets were synthesized via ultrasonic and graft methods. The complex permittivity, Cole-Cole plots, and reflection loss (RL) curve and 3D RL plots indicate that the nanosheets have remarkable absorption properties. When the content of (M/MoS2)/rGO was 18 wt %, (M/MoS2)/rGO wax composites exhibited an effective radar absorption bandwidth of 5.81 GHz at a thickness of 2.5 mm and a maximum RL of -49.7 dB. (M/MoS2)/rGO composites could be used as promising materials for RWA and broad absorption properties.
