A novel kind of reduced graphene oxide (RGO)/Fe3O4/Ag composite was firstly synthesized by a rational route. The RGO/Fe3O4/Ag composite shows the maximum absorption of -58.1 dB at 9.0 GHz with the thickness of 2.6 mm, and the absorption bandwidth with the reflection loss below -10 dB is up to 13.4 GHz (from 4.6 to 18.0 GHz) with a thickness in the range of 1.5-4.0 mm, suggesting that the microwave absorption properties and the absorption bandwidth are obviously enhanced by adding Ag NPs. It is believed that such composite could be used as a kind of candidate microwave absorber. (C) 2013 Elsevier B.V. All rights reserved.
