摘　　要：利用自组装的方法实现碳纳米管的有序排列对制备碳纳米管基复合材料至关重要.将聚4-乙烯基吡啶修饰的碳纳米管与含有羧基的接枝共聚物聚丙烯酸-g-聚甲基丙烯酸甲酯(PAA-g-PMMA)相混合,由于吡啶基团与羧基之间的氢键作用,在聚合物微相分离的过程中,将诱导形成碳纳米管的有序排列,得到一种基于碳纳米管自组装的蜂窝状膜.It is of importance for the application of carbon nanotubes in composite materials via supramolecular self-assembly of surface-functionalized carbon nanotubes. Here the self-assembly of the mixture of poly（4-vinylpyridine） functionalized multi-walled carbon nanotubes and carboxyl-containing graft copolymer, poly（acrylic acid）-g-poly（methyl methacrylate） is reported. Because of the hydrogen bond between the pyridine nitrogen and the carboxyl of the graft copoly- mer, carbon nanotubes were induced to form organized structure during the polymer microphase separation process, which afforded a kind of honeycomb suprastructure containing carbon nanotubes.
