▎ 摘  要

Reduced graphene oxide/Ni0.4Zn0.4Co0.2Fe2O3 (rGO/NZCF) nanocomposites were synthesized via facile hydrothermal reactions of rGO and metal nitrate. Transmission electron microscopy and scanning electron microscopy revealed that uniform NZCF particles with diameters of approximately 26.6 nm were homogeneously distributed on the rGO nanosheets. The electromagnetic properties and microwave absorption properties were determined of nanocomposites prepared with different rGO-to-NZCF weight ratios (m(rGO):m(NZCF)). When the value of m(rGO):m(NZCF) is 1:10, the rGO/NZCF nanocomposite with a thickness of 3 mm achieved a maximum reflection loss of -57.6 dB at 10.1 GHz and an effective adsorption frequency bandwidth of 4.2 GHz between 8.2 GHz and 12.4 GHz, which almost covers the whole X band. Therefore, the obtained composites are potential candidates for applications in microwave absorption. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
