One-step hydrothermal synthesis and microwave electromagnetic properties of RGO/NiFe2O4 composite
Source abstract
Abstract
Abstract The reduced graphene oxide (RGO)/NiFe 2 O 4 composite was synthesized by a facile one-pot hydrothermal route, which avoided the usage of chemical reducing agent. The reduction of graphene oxide (GO) and the crystallization of NiFe 2 O 4 crystals happened in a one-step hydrothermal process. The morphology, microstructure and magnetic properties of the composite were detected by means of XRD, XPS, TEM, EDX, TG-DSC and VSM. The maximum R L of the RGO/NiFe 2 O 4 composite is −39.7 dB at 9.2 GHz with the thickness of 3.0 mm, and the absorption bandwidth with the R L below −10 dB is up to 5.0 GHz (from 12.7 to 17.7 GHz) with a thickness of 1.9 mm. The introduction of RGO signally enhanced microwave absorption performance of the NiFe 2 O 4 NPs. It is believed that such composite will be applied widely in microwave absorbing area.
