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 copolymer, carbon nanotubes were induced to form organized structure during the polymer microphase separation process, which afforded a kind of honeycomb suprastructure containing carbon nanotubes.

Key words: carbon nanotube, self-assemble, microphase separation, composite materials
