Title:

GRAPHENE-COATED STEEL SHEET, AND METHOD FOR MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2012/064102

Kind Code:

A3

Abstract:

The present invention relates to a graphene-coated steel sheet, and to a method for manufacturing same. The graphene-coated steel sheet of the present invention comprises: a steel sheet; and a graphene layer formed on the steel sheet. Thus, a graphene-coated steel sheet is provided in which the corrosion of iron, such as the oxidation of iron, is prevented, and which has remarkably excellent thermal conductivity and electrical conductivity, as well as superior heat resistance resulting from the thermal stability of graphene. In addition, the method for manufacturing the graphene-coated steel sheet according to the present invention enables the manufacture of a high-quality graphene-coated steel sheet having grains of a single shape and little or no defects or impurities.
