摘要

采用颗粒堆积法

以石英砂为骨料

甲基纤维素为黏结剂干压成型后

在1300℃保温1 h烧结制备得到SiO2多孔陶瓷样品。通过对样品吸波性能的测试

发现样品的吸波带较宽达到9 GHz

反射率约-3 dB。经过浸渍氧化石墨烯后

样品的吸波性能发生较大改变。在氧化石墨烯质量分数为0.004%时

由于氧化石墨烯的涡流损耗

样品的吸波性能较纯SiO2多孔陶瓷样品的吸波性能提高75%

反射率达到-5 dB。过量的氧化石墨烯使多孔陶瓷样品呈现出对电磁波的全反射。

Abstract

A particle packing method was developed to prepare porous silica ceramics aggregated by sintering silica powder with methyl cellulose as binding agent at 1300℃ for 1 h.The result of electromagnetic wave absorption showed obvious electromagnetic wave absorption properties with a bandwidth of 9 GHz and-3 dB reflectivity.The electromagnetic wave absorption properties changed after graphene oxide (GO)layers were incorporated into the samples.When the mass fraction of graphene oxide impregnated samples was 0.004%

an increase of 75% in absorption was observed with the greatest reflectivity of-5 dB.The eddy current damping caused by these GO layers was responsible for the enhanced absorption efficiency.While excess GO made the porous sample to be a reflector for incident waves.
