Polymeric composition for hydrophilic separation membrane containing sulfonated carbon nano tubes and sulfonated graphene oxides

摘要

The present invention relates to a hydrophilic separation membrane polymer composition comprising a sulfonated graphene oxide and a sulfonated carbon nanotube, and a hydrophilic separation membrane manufactured therefrom. The hydrophilic separation membrane of the present invention has an advantage of high water permeability and excellent anti-staining properties. In the polymer composition for manufacturing a hydrophilic membrane according to an embodiment of the present invention, the sulfonated graphene oxide may have an atomic ratio of sulfur atoms to carbon atoms of 10 to 40% on the surface.
