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.
