摘　　要：本文利用碳纳米管的高比表面性质,使多壁碳纳米管(MWNT)表面吸附大量苯乙烯和过氧化苯甲酰(BPO)后在90℃加热,合成聚苯乙烯(PS)接枝修饰的MWNT。并采用透射电镜(TEM),高倍透射电镜(HR-TEM),场发射扫描电镜(FEW SEM),拉曼光谱(RAMAN),X光电子能谱(XPS),热重(TG)等对功能化后的MWNT进行了分析,证明了确实有大量的PS通过共价键接枝在MWNT表面。Based on the high specific surface area of muhiwall carbon nanotubes （MWNTs）, a massive of styrene and benzoyl per oxide （BPO） are absorbed onto their surface. PS - grafted MWNTs are fabricated by heating the above sample at 90℃ . The functionalized MWNTs are characterized by TEM, HRTEM, FESEM, Raman, TG and XPS. All characterization results suggest that the many PS chains have actually been attached to MWNTs by covalent bonds.
