聚二甲基硅氧烷/多壁碳纳米管复合材料中增强电磁干扰屏蔽的固体和空心玻璃微球的对比研究
Abstract(#br)Herein, solid and hollow glass microspheres (SGM and HGM) were added into polydimethylsiloxane/multi-walled carbon nanotube (PDMS/MWCNT) composites to induce multiple interfaces. The electromagnetic interference (EMI) shielding of the PDMS/MWCNT composites was expectedly enhanced by the multiple reflection and/or scattering at the interfaces between GM and PDMS/MWCNT phase. The EMI shielding effectiveness (SE) of the PDMS/MWCNT composites with 3.0 vol% MWCNT fillers increased from ~40 to ~52 dB and ~46 dB by the addition of 30 vol% SGM and HGM, respectively.
