▎ 摘　　要

NOVELTY - The method for preparing graphene/polyester composite fiber, involves (1) chemically reducing concentration of 1-2 mg/mL graphene oxide suspension to obtain black suspension, (2) immersing polyester fiber in black suspension in mass ratio of 1:20-40 for 2-3 days, removing the polyester fiber and drying. USE - Method for preparing graphene/polyester composite fiber for decolorization of dye wastewater (claimed). ADVANTAGE - The method enables simple preparation of recyclable graphene/polyester composite fiber with high stability, simple dye decolorization process and low operation cost.
