Abstract

Abstract : A ternary spherical composite was synthesized by a solvothermal method and its microwave absorption properties were studied. Abstract : A reduced graphene oxide/FeNi3 /Fe3 O4 composite was successfully synthesized by a one-pot solvothermal reduction method. The microstructure and morphology were confirmed through X-ray diffraction and scanning electron microscopy. The loss tangent parameters showed that the electromagnetic attenuation mechanism of RGO/FeNi3 /Fe3 O4 is mainly dependent on dielectric loss. The microwave absorption properties showed a maximum absorption of −46.6 dB at 12.5 GHz with a thickness of 1.9 mm. The absorption bandwidth with reflection loss below −20 dB is increased by 9.26 GHz (from 6.1 to 15.36 GHz) with a thickness in the range of 1.6–3.5 mm. The excellent microwave absorption properties of RGO/FeNi3 /Fe3 O4 make it a candidate for a microwave absorptive material.
