▎ 摘　　要

NOVELTY - Surface-treated steel sheet comprises a steel sheet substrate and graphene containing polymer resin layer at the upper part of the steel sheet substrate, where graphene is arranged in the direction towards the steel sheet substrate or surface of polymer resin layer. USE - Used as surface-treated steel sheet. ADVANTAGE - The surface-treated steel sheet exhibits excellent corrosion resistance and thermal conductivity characteristics and includes polymer resin layer of uniform and constant thickness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing the surface-treated steel sheet, comprising preparing steel sheet substrate, coating graphene containing polymer resin composition on steel sheet substrate, drying and curing to form resin layer, where voltage of -200 to 200 V (excluding 0 V) is applied on steel sheet substrate during drying process and graphene is arranged within the polymer resin layer.
