In this work, hybrid nanocomposites of reduced graphene oxide/multi-walled carbon nanotubes/zinc ferrite (RGO/MWCNTs/ZnFe2O4) were fabricated by a facile one-pot hydrothermal strategy. Effect of the mass ratio of GO to MWCNTs on the structure, morphology, magnetic properties and microwave absorption properties of the as-prepared hybrid nanocomposites was investigated in detail. Results demonstrated that the surface of MWCNTs were loaded with ZnFe2O4 nanoparticles and interlinked with RGO, which constructed the three-dimensional (3D) conductive networks in the ternary nanocomposites. Moreover, the ternary nanocomposites exhibited enhanced microwave absorption with the minimum reflection loss of 23.8 dB and effective absorption bandwidth (less than 10 dB) of 2.6 GHz. Significantly, the dual-waveband absorption characteristics covering the C and Ku bands were observed. Therefore, the obtained hybrid nanocomposites were potential candidates for application in the field of microwave absorption.
