▎ 摘　　要

NOVELTY - Manufacture of film involves preparing a carbon nanotube-graphene-coated copper nanowires and preparing mixture by mixing carbon nanotube-graphene-coated copper nanowires with ionic polymer solution. USE - Manufacture of film used for capacitor. ADVANTAGE - The method enables manufacture of film having excellent electric current density and electron transport property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for film, which comprises a core-shell structure comprising the copper nanowires as core and the carbon nanotube-graphene as shell for carbon nanotube-graphene-coated copper nanowires, and the ionic polymer.
