Abstract
Disclosed is a paint composition containing graphene oxide for preventing corrosion of a structure and improving water repellency, corrosion proof and long-term durability of a concrete structure. The paint composition includes a powder mixture containing 0.2 to 1.0 weight % of zinc (Zn), 0.02 to 0.3 weight % of graphene oxide, 0.06 to 0.11 weight % of phosphorus, and a remaining amount of aluminum (Al); and an adhesive resin in which the powder mixture is uniformly dispersed.
