Radar Absorbing Nanocomposites Based MultiLayered Graphene Platelets/Epoxy

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.
