Title:
COPPER FOIL FOR GRAPHENE PRODUCTION, AND GRAPHENE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2014/128834
Kind Code:
A1
Abstract:
[Problem] To provide a copper foil for graphene production and a graphene production method using the copper foil, whereby it is possible to produce high-quality large-area graphene at low cost. [Solution] A copper foil (10) for graphene production which comprises a plated Cu layer and/or a sputtered Cu layer and has a surface roughness (Rz) of 0.5 μm or less, with at least 60% of the surface being constituted by the (111) plane.
