采用等离子体聚合技术在多壁碳纳米管(MWNTs)表面聚合苯乙烯(Styrene)、吡咯(Pyrrole)有机膜.高分辨电镜(HRTEM)分析显示MWNTs内外表面均生成纳米级厚度的有机膜,其中外壁表面厚约7 nm,内壁表面厚约1～3 nm.将经过表面有机膜处理的MWNTs添加到聚苯乙烯中,制备出多壁碳纳米管/聚苯乙烯(MWNTs/PS)复合材料.扫描电镜(SEM)对MWNTs/PS复合材料分析表明,覆膜的MWNT在复合材料中的分散得到改善.通过力学拉伸试验测试了MWNTs/PS复合材料断裂强度和弹性模量与MWNTs含量的关系,证明了经有机覆膜处理的MWNTs与PS形成的复合材料的整体强度得到显著提高.
