进行了用苯氨单体在含有分散碳纳米管的环境中发生聚合,使聚苯胺包覆碳纳米管,然后把这些碳纳米管添加到聚丙烯中的实验.利用透射电子显微镜,X射线衍射仪对碳纳米管的分散效果,碳纳米管/聚苯胺界面进行了分析,检测.对加有碳纳米管/聚苯胺的聚丙烯进行了抗拉强度测试,并对试样弯曲断裂断口进行了扫描电镜分析和EDS分析.结果表明苯胺可以很好地在碳纳米管上形核聚合,形成的聚苯胺能够完全包覆和缠绕在碳纳米管上,从而有利于碳纳米管处于很好的分散状态.包覆有聚苯胺的碳纳米管添加到聚丙烯中提高了聚苯烯的力学性能,与不添加填料的聚苯烯相比,在相同实验条件下添有包覆聚苯氨的碳纳米管2%的聚苯烯常温拉伸强度提高了70%.
