Title:
METHOD FOR PREPARING OF COMPOSITION FOR SURFACE TREATMENT OF METAL, SURFACE-TREATED STEEL SHEET USING SAME AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2014/069716
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a composition for the surface treatment of metal, a surface-treated steel sheet which is surface-treated with the composition and to a method for manufacturing the surface-treated steel sheet. To accomplish the objective, the method of the present invention may involve the preparing of a composition for the surface treatment of metal using graphene having superior characteristics such as corrosion resistance, electrical conductivity and thermal conductivity. The composition may be effectively coated onto the metal surface by means of electrophoresis, and thus a highly functional surface-treated steel sheet can be obtained.
