Abstract

Abstract The aim of this research is to measure the dielectric properties and electromagnetic interference (EMI) shielding effectiveness (SE) of silicone rubber reinforced with graphene nanoplates. In a two-roll mill, different amounts of graphene are mixed together. This is followed by compression moulding at 170°C and post-curing for 4 h at 200°C. Between 1 MHz and 1 GHz, the waveguide transmission line method and a vector network analyser are used to measure the dielectric and EMI SE parameters. As the amount of graphene is increased from 0 to 7 wt%, AC conductivity goes up, reaching 1.19 × 10−3 S/cm at 7 wt%. The same composition gives the highest EMI SE of 43.22 dB at 1 GHz. The high-frequency structural simulation of different compositions shows how shielding works, and the results agree with what has been seen in experiments.

石墨烯增强硅橡胶纳米复合材料的介电性能和电磁屏蔽效果评价

摘要本研究的目的是测量石墨烯纳米板增强硅橡胶的介电性能和电磁干扰屏蔽效果。在两辊轧机中，不同数量的石墨烯混合在一起。然后在170°C下进行压缩成型并进行4次后固化 h。介于1之间 MHz和1 GHz、波导传输线法和矢量网络分析仪用于测量电介质和EMI SE参数。随着石墨烯的数量从0增加到7 wt%，交流电导率上升，达到1.19×10−3 S/cm，7 重量%。相同成分的EMI SE最高，为43.22 1时的dB GHz。不同成分的高频结构模拟显示了屏蔽的工作原理，结果与实验结果一致。

期刊介绍： The bimonthly journal Nanotechnology Reviews provides a platform for scientists and engineers of all involved disciplines to exchange important recent research on fundamental as well as applied aspects. While expert reviews provide a state of the art assessment on a specific topic, research highlight contributions present most recent and novel findings. In addition to technical contributions, Nanotechnology Reviews publishes articles on implications of nanotechnology for society, environment, education, intellectual property, industry, and politics.
