Radar Absorbing Nanocomposites Based MultiLayered Graphene Platelets/Epoxy

در اين مقاله نانوساختار گرافني با روش هامر سنتز شد. در صدهاي وزني 1، 3، 5 و 7 از گرافن به رزين اپوكسي افزوده شد. نانوساختارسنتز شده توسط پراش اشعه X، ميكروسكوپ الكتروني روبشي واسپكتروسكوپي مادون قرمز شناسايي شد. پوششش تداخلي الكترومغناطيسي با روش حذف بازتاب بررسي شد. نتايج نشان داد كه 3درصد وزني از گرافن بهترين نتيجه را براي تست جذب امواج رادار دارد.

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.
