| 摘要 |
The present invention relates to a galvanized steel sheet having a treated surface and a manufacturing method thereof. The surface of the galvanized steel sheet is treated to enhance anti-corrosion properties of the galvanized steel sheet used for a material for a vehicle body, vehicle parts, or home appliances. According to the present invention, graphene having excellent physical properties such as electrical conductivity is formed in the shape of a layer having a certain thickness between a plating layer and a resin layer, formed to increase anti-corrosion properties, of the galvanized steel sheet. Therefore, the galvanized steel sheet having a treated surface, which has not only excellent anti-corrosion properties but also excellent electrical conductivity, can be manufactured. |
