A magnetic reduced graphene oxide (MRGO) composite consisting of graphene oxide and Fe3O4 particles in the range of 5-20 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 (R-L) value of -49.05 dB has been observed at 14.16 GHz with a thickness of 2.08 mm. The absorption bandwidth (R-L < -10 dB) corresponding to the minimum R-L is 4.60 GHz. The electromagnetic wave absorption properties of the RGO-Fe3O4 composite have been interpreted through the quarter-wavelength matching model. (C) 2016 Elsevier Ltd and Techna Group S.r.l.
