▎ 摘　　要

NOVELTY - A graphene-modified sodium alginate-polyacrylonitrile hetero-reinforced hollow fiber membrane comprises polyacrylonitrile-sodium alginate dense layer modified with graphene and enhanced with heterogeneous body by coating with a casting solution to form graphene-modified sodium alginate-polyacrylonitrile hetero-reinforced hollow fiber membrane. USE - Graphene-modified sodium alginate-polyacrylonitrile hetero-reinforced hollow fiber membrane. ADVANTAGE - The hollow fiber membrane has high water vapor permeability, excellent separation performance, better protein filtration flux, improved mechanical property, improved tensile breaking strength and high selectivity.
