摘要：
The reduced graphene oxide (RGO) coated with Fe3O4 composite was synthesized through a facile one-pot simplified co-precipitation route, which avoided the usage of inert gas and any additional chemical agents (such as surfactants). Given these advantages, the strategy described in this study can be developed as a simple and large-scale yield route to RGO/Fe3O4 composite. The RGO/Fe3O4 composite shows the maximum absorption of -44.6 dB at 6.6 GHz with the thickness of 3.9 mm, and the loss mechanism is mostly dielectric loss. It is believed that such composite will find its wide applications in microwave absorbing area. (C) 2013 Elsevier B.V. All rights reserved.
