Abstract

The present invention relates to a surface-treated steel plate and to a production method for same, and more specifically relates to a surface-treated steel plate having outstanding corrosion resistance and thermal conductivity. In order to achieve this aim, in the present invention a macromolecular resin composition comprising graphene, which has highly outstanding physical properties including electrical conductivity, is coated onto the surface of a steel foundation plate, thereby making it possible to provide a surface-treated steel plate able to supremely well ensure not only corrosion resistance but also the intrinsic characteristics of graphene due to the macromolecular resin composition.
