▎ 摘　　要

NOVELTY - A graphene-modified sodium alginate-PVC-reinforced hollow fiber membrane has a dense layer of PVC-alginate and alginate layer made of graphene in which homogeneous reinforcement surface is casted with casting solution to form graphene modified sodium alginate-PVC hollow fiber membrane. USE - Graphene-modified sodium alginate-PVC-reinforced hollow fiber membrane. ADVANTAGE - The membrane has high water vapor permeability and excellent separation, improved mechanical property, and tensile breaking strength of the film.
