摘　　要：以多壁碳纳米管为导电剂,通过十八胺修饰改性,使用常规印刷技术,将经过十八胺修饰后的碳纳米管沉积于纸纤维网络上,制成可运用于电子器件的碳纳米管导电纸,并运用扫描电子显微镜、矢量网络分析仪、红外光谱仪与表面电阻测量仪对其进行表征。结果表明,经过十八胺修饰过的碳纳米管,其分散性能提高,表面电阻率大幅度下降,电磁屏蔽性能大幅提高。Electrically conductive paper was made by multi-wall carbon nanotubes （MWCNTs） which were used as electrical conductive filler and modified by octadecylamine（ODA）. Shielding effectiveness （SE）, infra-rad（IR）, scanning electron microscopy（SEM） and surface resistivity （SR） are used to characterize the properties of carbon nanotubes and the electrically conductive paper. The result shows ODA can substantially improve the dispersion property. So the electrically conductive and electromagnetic interference shielding properties of the paper are enhanced.
