摘 要：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 ℃ in mixture of gases:argon（Ar）,hydrogen（H2）,and methane（CH4）.Then,carbon nanotubes（CNTs） were grown uniformly on the surface of graphene/Cu films at 750 ℃ in mixture of Ar,H2.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.
