ZIF-8衍生的ZnO与RGO复合材料的制备及其电磁波吸收性能
Preparation and electromagnetic wave absorption properties of zeolitic imidazolate framework-8 derived ZnO and reduced graphene oxide composites
摘要
Abstract
The authors used ZIF-8 and GO as raw materials.The MOFs-derived ZnO and RGO (ZnO/RGO)composites were prepared by the wet chemical method and carbonization process.The structure and phase of as-prepared products were analyzed by X-ray diffraction, scanning electron microscopy and transmission electron microscopy.Meanwhile, the electromagnetic parameters (complex permittivity and complex permeability)of ZnO/RGO composites were investigated by the vector network analyzer.The microwave absorption properties of the ZnO/RGO composites with different thicknesses were calculated and the results showed that the samples with the calcination temperature of 700 ℃ had good microwave absorbing performance in the frequency range of 2-18 GHz.It had a maximum absorption of-22.9 dB at 17.2 GHz and the effective absorption(below -10 dB)bandwidth was up to 1.0 GHz (from 1 6.8 GHz to 1 7.8 GHz)with thickness of 4 mm.关键词
