GRAPHENE OXIDE, GRAPHENE-POLYMER COMPLEX, COATING SOLUTION CONTAINING SAME, GRAPHENE-POLYMER COATED STEEL SHEET, AND METHOD FOR MANUFACTURING THEREOF

摘要

Provided are a graphene oxide, a graphene-polymer complex, a coating solution containing same, a graphene-polymer complex-coated steel sheet, and a method for manufacturing same. According to the present invention, a steel sheet is provided, in which graphenes can be directly coated to a base steel sheet without using a separate binder and said graphenes can be located on a coating layer, thus properties of the graphenes can be efficiently exhibited.
