▎ 摘　　要

The reduced graphene oxide (RGO)-Ni0.5Zn0.5Fe2O4 composite was synthesized by a facile route. The morphology, microstructure and microwave electromagnetic properties of the composite were detected by means of TEM, SEM, XRD, XPS and vector network analyzer. The maximum reflection loss (R-L) of the RGO-Ni0.5Zn0.5Fe2O4 reaches -47.8 dB at 10.7 GHz with the thickness of 2.8 mm, and the absorption bandwidth with RL below -10 dB is up to 11.4 GHz (from 6.6 to 18.0 GHz) with the thickness in the range of 2.0-4.0 mm. It is believed that such composite will be applied widely in microwave absorbing area. (C) 2015 Elsevier B.V. All rights reserved.
