▎ 摘　　要

NOVELTY - Manufacturing fiber yarns coated with reduced graphene oxide, comprises (a) swelling (S101) hydrophobic fiber yarns, (b) coating (S102) graphene oxide on swollen fiber yarns by immersing the swollen fiber yarns in polar aprotic solvent dispersed with graphene oxide, and (c) reducing (S103) the graphene oxide, where the hydrophobic fiber yarn is made up of polypropylene. USE - The method is useful for manufacturing fiber yarns coated with reduced graphene oxide (claimed). ADVANTAGE - The method maximizes the hydrophobicity of the fiber yarn by coating with the hydrophobic reduced graphene oxide, and thus it is suitable for wastewater treatment process in inhibiting the absorption of pollutants and reduces backwashing cycle and exchange period. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic process flow for manufacturing fiber yarns coated with reduced graphene oxide (Drawing includes non-English language text).
