COPPER FOIL FOR GRAPHENE PRODUCTION, METHOD FOR PRODUCING COPPER FOIL FOR GRAPHENE PRODUCTION, AND METHOD FOR PRODUCING GRAPHENE

摘要

PROBLEM TO BE SOLVED: To provide copper foil for graphene production capable of inexpensively producing graphene having a large area, and to provide a method for producing graphene using the same.;SOLUTION: In a copper foil for graphene production, the total of each crystal grain boundary length per unit area on the surface is ≤0.00800 μm/μm², after being heated at 1,000°C for one hour in an atmosphere containing ≥20 vol% hydrogen and having argon as the residue.;COPYRIGHT: (C)2014,JPO&INPIT
