Abstract: | In this work,a stable,large area sandwich structure of material consisted of carboxylic multiwall carbon nanotubes(c-MWCNTs) and polymer-modified graphene(G) via a self-assembly process was prepared.Positively charged nanomaterial of polymer-modified graphene were prepared via in situ reduction of graphite oxide in the presence of poly(diallyldimethylammonium chloride)(PDDA).Then c-MWCNTs were added into the water-soluble PDDA-modified graphene to form hybrid carbon material via sequential electrostatic self-assembly.Transmission electron microscope(TEM) and scanning electron microscopy(SEM) were used to characterize those hybrid materials.From the figures we can learn that this method has successfully led to the fabrication of a reasonably uniform film with well-interconnected carbon-based hybrid materials. |
