▎ 摘　　要

NOVELTY - A graphene-modified sodium alginate-polyacrylonitrile hollow fiber membrane comprises a polyacrylonitrile support layer, where the hollow fiber membrane is obtained by compounding a sodium alginate layer on the inner surface of the polyacrylonitrile support layer and modifying the resultant layer with graphene to form the hollow fiber membrane, the polyacrylonitrile support layer and the sodium alginate layer are anisotropic in thickness, the tensile break strength of the hollow fiber membrane is 600-1000 MPa, and the thickness of the hollow fiber membrane is 50-300 mu m. USE - Graphene-modified sodium alginate-polyacrylonitrile hollow fiber membrane. ADVANTAGE - The graphene-modified sodium alginate-polyacrylonitrile hollow fiber membrane has better tensile breaking strength.
