▎ 摘  要

NOVELTY - A high-throughput hollow fiber desalting film comprises 1-5 pts. wt. porous carbon nanosheet , 25-35 pts. wt. high molecular resin powder , 55-65 pts. wt. N, N-dimethylacetamide , 1-5 pts. wt. hydrophilic agent and 5-10 pts. wt. pore-forming agent. The porous carbon nanosheet is prepared by dispersing graphene oxide to organic solution. USE - High-throughput hollow fiber desalting film. ADVANTAGE - The high-throughput hollow fiber desalting film has strong hydrophilicity, high flux, high desalting rate and good strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high-throughputhollow fiber desalination membrane, which involves: (A) mixing the high molecular resin powder, N, N-dimethyl acetamide, hydrophilic agent, pore-forming agent uniformly; (B) adding porous carbon nano sheet; (C) continuously mixing and stirringuniformly to obtain the base film; (D) soaking base film in the water phase with the temperature of 60-80 degrees C for 50-70s; (E) taking out and draining thewater and soaking it in the organic phase for 50-70s; and (F) solidifying and shaping.
