摘要
以包覆在碳纳米管表面的薄层二氧化锰作为表面再包覆聚苯胺的反应性模板合成了聚苯胺和碳的复合的多壁纳米管的结构，该复合材料在水中显示出很好的分散性．该方法还可以用来合成如聚3，4乙撑二氧噻吩、聚吡咯、二氧化硅、无定形碳等材料与碳纳米管的复合材料。
Multishell nanotubes of polyaniline and carbon were synthesized via a template approach. A thin layer of MnO2 coated on carbon nanotubes acts as a reactive template for the consequent formation of the polyaniline coating. The polyaniline-carbon nanotubes show enhanced dispersibility in water and can be possibly used as a functional material of electrochemical capacitors with improved performance. The general method operates by coating carbon nanotubes on functional materials such as poly （3,4-ethylenedioxythiophene）, polypyrrole, silica, and carbon.
