▎ 摘　　要

NOVELTY - A copper metal wire or nickel metal wire is prepared and converted in desired shape of graphene pipe. The template structure chemical vapour deposition cavity is heated, annealed and cooled. The resultant product is coated with polymethyl methacrylate protective coating, and heated. The metal wire is coated with multifunctional poly(methyl methacrylate) graphene. The poly(methyl methacrylate)graphene thin film is coated with benzaldehyde, substrate is covered using nitrogen and dried, to obtain poly(methyl methacrylate) multifunctional graphene tube. USE - Manufacture of multifunctional graphene tube. ADVANTAGE - The method provides multifunctional graphene tube with high quality, stability, transparency, conductivity and definite shape. DETAILED DESCRIPTION - A copper metal wire or nickel metal wire as template is prepared and converted into desired shape of the graphene pipe template. The template structure chemical vapour deposition cavity is added in the constant temperature section, quartz tube is sealed, vacuumized at 10-15 Pa, argon gas is introduced, heated at 950-1000 degrees C in hydrogen and argon atmosphere for 30-40 minutes, annealed in argon atmosphere and cooled to room temperature. The resultant product is coated with polymethyl methacrylate protective coating, and heated at 130-150 degrees C for 5 minutes with low speed 600-620 rpm/10 seconds. The graphene tube is dissolved in sulfur oxide (0. 1-0.2 mol/L). The graphite alkene is dissolved in iron chloride. The metal wire is provided in the water and coated with multifunctional poly(methyl methacrylate) graphene. The poly(methyl methacrylate) graphene thin film is coated with benzaldehyde, melted for absorbing the organic solvent on the edge, repeated for 2-3 times, substrate is covered under nitrogen atmosphere and dried, to obtain poly(methyl methacrylate) multifunctional graphene tube.
