Abstract

RGO (reduced graphene oxide)-Fe3O4 nanohybrids were successfully synthesized by a solvothermal reduction method. Fe3O4 nanoparticles, RGO and the nanohybrids were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectroscopy and vibrating sample magnetometer (VSM). The electromagnetic interference (EMI) shielding effectiveness (SE) of RGO-Fe3O4/SF/PP composite was much higher than that of Fe3O4/SF/PP composite at 8-12 GHz, which was attributed to synergistic effect between RGO and Fe3O4 nanoparticles. The EMI SE (%) improved with the increase of RGO-Fe3O4 content and the maximum value of 80.44% was obtained for the RGO-Fe3O4/SF/PP composite. Furthermore, the dominant shielding mechanism of RGO-Fe3O4/SF/PP was absorption.
