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 widespread applications in the military field. In this paper, silanized MoS 2 (M/MoS 2 )/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/MoS 2 )/rGO was 18 wt %, (M/MoS 2 )/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/MoS 2 )/rGO composites could be used as promising materials for RWA and broad absorption properties.
