| 7 | A Simple Approach to the Fabrication of Graphene-Carbon Nanotube Hybrid Films on Copper Substrate by Chemical Vapor Deposition显示文摘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(H_2),and methane(CH4).Then,carbon nanotubes(CNTs) were grown uniformly on the surface of graphene/Cu films at 750 ℃ in mixture of Ar,H_2.and acetylene(C_2H_2) gases.Ferric salt FeCl_3 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 FeCl_3 salt catalyst. | Nguyen Van Chuc Cao Thi Thanh Nguyen Van Tu Vuong T.Q Phuong Pham Viet Thang Ngo Thi Thanh Tam | 2015 | Journal of Materials Science & Technology2015，31，5： | 0 |
