Radar Absorbing Nanocomposites Based MultiLayered Graphene Platelets/Epoxy

摘要

Graphene nanostructures were synthesized by Hummer method. 1, 3, 5 and 7 wt% of graphene nanostructures were suspended in certain amount of acetone on a mechanical stirrer and stirred then added to epoxy resin. After 4 hours, solution and Graphene platelets (GPs) were prepared. Nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM ), Fourier transform infrared (FT-IR) spectroscopy. The electromagnetic interference shielding was studied by reflection loss (RL). According to the results, the multilayered graphene 3% wt of has a completely smooth surface and its absorption average and maximum are reported as -13.5 dB and -30.3 dB.
