Abstract:
The present invention relates to a reduced graphene oxide-coated filament that inhibits the adsorption of pollutants when applying a filament filter in a wastewater treatment process, thereby enabling a long-term usage of the filament filter by coating the hydrophobic filament with reduced graphene oxide (RGO) and maximizing the hydrophobicity of the filament; and to a manufacturing method thereof. The method for manufacturing a reduced graphene oxide-coated filament according to the present invention comprises the steps of: swelling the hydrophobic filament; coating the swollen filament with graphene oxide (GO) by immersing the swollen filament in a polar aprotic solvent having the graphene oxide (GO) dispersed therein; and reducing the graphene oxide (GO).
Abstract:
The present invention relates to a reduced graphene oxide coated fiber yarn and a method for manufacturing the same which suppresses adsorption of contaminants when a fiber yarn filter is applied to a wastewater treatment process by maximizing hydrophobicity of the fiber yarn by coating a hydrophobic fiber yarn with reduced graphene oxide (RGO), thereby allowing the fiber yarn filter to be used for a long time. The manufacturing method of the reduced graphene oxide coated fiber yarn according to the present invention comprises the steps of: swelling the hydrophobic fiber yarns; coating the swollen fiber yarns with graphene oxide (GO) by immerging the swollen fiber yarns in a polar aprotic solvent in which the GO is dispersed; and reducing the GO.
