Title:
ELECTROLYTIC COPPER FOIL FOR GRAPHENE AND METHOD FOR PRODUCING FORMER
Document Type and Number:
WIPO Patent Application WO/2017/188600
Kind Code:
A1
Abstract:
The present invention relates to electrolytic copper foil for graphene and a method for producing the former, more specifically to electrolytic copper foil for graphene capable of facilitating graphene formation due to prevention of surface deformation of the electrolytic copper foil during production of same, and to a method for producing the electrolytic copper foil for graphene. According to the present invention, by providing electrolytic copper foil, for graphene, having roughness Rz on surface S expressed by the formula 1 after an hour of treatment at 200°C during synthesis of graphene on the electrolytic copper foil, the surface deformation of the electrolytic copper foil at high temperatures can be minimized. Furthermore, according to the present invention, by providing electrolytic copper foil having a low resistance value of 300Ω/square or less after the synthesis of graphene thereon, graphene can be easily formed the electrolytic copper foil.
