Abstract
A magnetic reduced graphene oxide (MRGO) composite consisting of graphene oxide and Fe3O4 particles in the range of 5-20Â nm has been prepared by the one-pot hydrothermal process. RGO nanosheets provide flexible substrates for nanoparticle decoration, while Fe3O4 nanoparticles can also effectively prevent nanosheets to restack each other. Compared with previously literature, the synthesized RGO-Fe3O4 composite exhibits excellent electromagnetic wave absorption. The minimum reflection loss (RL) value of â49.05Â dB has been observed at 14.16Â GHz with a thickness of 2.08Â mm. The absorption bandwidth (RL<â10Â dB) corresponding to the minimum RL is 4.60Â GHz. The electromagnetic wave absorption properties of the RGO-Fe3O4 composite have been interpreted through the quarter-wavelength matching model.
