▎ 摘　　要

NOVELTY - Cathode roll (17) comprises graphene layer (17b) formed on cylindrical mold (17a) and pattern generating unit (17c) formed on the graphene layer. The pattern generating unit has fine pattern, where pitch of the fine pattern is 1-10cm and depth of the fine pattern is 1100nm-1mm. The graphene layer is graphene monolayer. USE - Cathode roll for manufacturing electroplated thin film (claimed). ADVANTAGE - The cathode roll manufactures electroplated thin film with deformity with high quality. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing electroplated thin film, which involves: (A) locating positive electrode below the negative electrode roll, and spacing apart from the negative electrode roll; (B) obtaining plating bath including negative electrode roll, positive electrode and electrolyte; and (C) using auxiliary roll for transporting the electroplated thin film formed on the negative electrode roll. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the cathode roll.
