▎ 摘　　要

NOVELTY - Manufacture of graphene/carbon nanotube composite conductive film involves preparing catalyst precursor, washing and drying copper foil, carrying out plasma treatment, preparing catalyst solution, soaking treated copper foil in catalyst solution such that layer of catalyst solution is loaded on copper foil, drying copper foil substrate to obtain yttrium-doped catalyst precursor uniformly distributed on copper foil substrate, putting catalyst precursor in constant temperature region in the middle portion of reaction tube, carrying out catalytic cracking reaction, and cooling. USE - Manufacture of graphene/carbon nanotube composite conductive film (claimed). ADVANTAGE - The graphene/carbon nanotube composite conductive film is manufactured efficiently with excellent workability. DETAILED DESCRIPTION - Manufacture of graphene/carbon nanotube composite conductive film involves preparing catalyst precursor, ultrasonically washing copper foil, drying copper foil, carrying out plasma treatment or micro-oxidization treatment on dried copper foil sample, preparing catalyst solution, soaking treated copper foil in the catalyst solution such that a layer of catalyst solution is loaded on a copper foil substrate, putting the copper foil substrate into vacuum drying box to dry for 1 hour to obtain yttrium-doped catalyst precursor uniformly distributed on copper foil substrate, putting the catalyst precursor in constant temperature region in the middle portion of reaction tube for decomposing reaction, heating to carry out catalytic cracking reaction for 0.2-1 hour, introducing a mixed reaction gas, preserving the temperature for 0-1 hour and reducing the furnace temperature to room temperature under the atmosphere of argon.
