In this study, graphene-carbon nanotube (CNT) hybrid films were directly synthesized on polycrystalline copper (Cu) substrates by thermal chemical vapor deposition (CVD) method. Graphene films were synthesized on Cu substrate at 1000 degrees C in mixture of gases: argon (Ar), hydrogen (H-2), and methane (CH4). Then, carbon nanotubes (CNTs) were grown uniformly on the surface of graphene/Cu films at 750 degrees C in mixture of Ar, H-2, and acetylene (C2H2) gases. Ferric salt FeCl3 solution deposited onto the surface of graphene/Cu substrate by spin coating method was used as precursor for the growth of the CNTs. The density and quality of the CNTs on the surface of graphene/Cu films can be controlled by varying the concentration of FeCl3 salt catalyst.
