▎ 摘　　要

NOVELTY - Graphene composite polyacrylonitrile hollow fiber membrane comprises 20-50 wt.% polyacrylonitrile powder, 0.1-15 wt.% graphene oxide solution, 0.1-1 wt.% modifier, 10-20 wt.% pore-forming agent and 30-60 wt.% solvent. The pore-forming agent includes mixture of inorganic salt, polyethylene glycol and ethyl cyanoacrylate in a mass ratio of 1:2-4:1-2. USE - Used as graphene composite polyacrylonitrile hollow fiber membrane. ADVANTAGE - The membrane has high strength and high filtration efficiency; removes suspended particles, heavy metals, colloids, bacteria and pathogens in the water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene composite polyacrylonitrile hollow fiber membrane.
