▎ 摘　　要

NOVELTY - An electrolytic copper foil has ratio of surface roughness of the copper foil and surface roughness of the copper foil after heat treatment of 0.05-0.2. USE - Electrolytic copper foil is used for producing graphene for fabricating semiconductor component for electronic paper, display and computer. ADVANTAGE - The electrolytic copper foil has excellent surface uniformity and surface deformation resistance, and can be manufactured by simple process, and is suitable for mass production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of electrolytic copper foil, which involves using an electrolytic solution.
