摘要

采用一锅法制备还原石墨烯与片状氧化镍复合材料。复合材料的结构形貌、晶型和电磁参数分别通过扫描电镜、透射电镜、X射线衍射仪以及HP8722ES型矢量网络分析仪进行表征、测试与分析。结果表明

还原石墨烯与片状氧化镍复合材料同纯还原石墨烯相比在低频段(2.0~6.6 GHz)有更佳的吸收宽度和微波吸收能力

还原石墨烯与氧化镍片复合材料的介电损耗显著增加。大尺寸氧化镍片与还原石墨烯紧密复合提高了材料的载流子迁移率

从而提高了材料的吸波特性。

Abstract

The reduced graphene oxide (RGO) coated with large area NiO nanosheets composites were synthesized through a facile one-pot simplified route. The morphology

crystallographic structures and microwave parameters of the composites were investigated by SEM

TEM

XRD and HP8722ES network analyzer. As a result

the RGO/NiO has a much higher reflection loss and wider bandwidth than pure RGO in the low frequency range (2.0-6.6 GHz). The RGO/NiO nanosheets have much higher dielectric loss properties. The interfacial affinity between NiO and GO may increase the numbers of conductive pathways for electron transfer and enhance microwave absorption property of composites consequently.
