Patent ID: 10826117

Abstract:
The present disclosure relates to an electrolytic copper foil for graphene and a method for producing the copper foil. More particularly, the present disclosure relates to an electrolytic copper foil for graphene and a method for producing the copper foil, which may facilitate formation of graphene by blocking surface deformation during the electrolytic copper foil formation. In accordance with the present disclosure, the Rz roughness of the S-face of the electrolytic copper foil after 1 hour treatment at 200° C. in the synthesis of graphene on the electrolytic copper foil is defined based on the Relationship 1 below. This may also minimize the deformation of the surface of the electrolytic copper foil at high temperatures: 0.05≤(Rz roughness of M-face of electrolytic copper foil/Rz roughness of S-face after treatment at 200° C. for 1 hour)/thickness of electrolytic copper foil≤0.2.  Relationship 1:
