Abstract 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.

RGO/MWCNTs/ZnFe 2 O 4 杂化纳米复合材料的简便制备和微波吸收性能

摘要 在这项工作中,还原氧化石墨烯/多壁碳纳米管/铁酸锌 (RGO/MWCNTs/ZnFe2O4) 的混合纳米复合材料通过简便的一锅水热策略制备。详细研究了 GO 与 MWCNT 的质量比对所制备的杂化纳米复合材料的结构、形貌、磁性能和微波吸收性能的影响。结果表明,MWCNTs 的表面负载有 ZnFe2O4 纳米颗粒并与 RGO 互连,从而在三元纳米复合材料中构建了三维 (3D) 导电网络。此外,三元纳米复合材料表现出增强的微波吸收,最小反射损耗为 -23.8 dB,有效吸收带宽(小于 -10 dB)为 2.6 GHz。显着地,观察到覆盖 C 和 Ku 波段的双波段吸收特性。因此,所获得的杂化纳米复合材料是在微波吸收领域应用的潜在候选者。
