▎ 摘　　要

NOVELTY - A graphene oxide/polyurethane hollow fiber ultrafiltration membrane comprises 25-50 mass% polyurethane, 2-10 mass% chlorinated PVC, 1-5 mass% graphene oxide, 5-10 mass% polyethylene glycol/polyvinyl pyrrolidone mixture, 1-5 mass% Tween-80 (RTM: Polysorabate) and 20-66 mass% dimethylacetamide, where the polyurethane having a weight average molecular weight of 350,000 and the chlorinated PVC having a weight average molecular weight of 65,000. USE - Graphene oxide/polyurethane hollow fiber ultrafiltration membrane. ADVANTAGE - The graphene oxide/polyurethane hollow fiber ultrafiltration membrane can be prepared with high film wire flux, better toughness and impact resistance and catalytic and antibacterial function. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing graphene oxide/polyurethane hollow fiber ultrafiltration membrane.
