▎ 摘  要

NOVELTY - Preparing membranes with enhanced water flux comprises (i) carrying out in-situ synthesis of nanoparticles-graphene material, preparing nanoparticle-graphene materials by solvothermal method; (ii) preparing liquid film by dispersing prepared nano-graphene material in solvent, applying of 0.1-0.5 mg/ml membrane-forming liquid, allowing to stand; and (iii) preparing membrane by loading support into membrane module, dispersing step (ii) configured nano-graphene under pressure on surface of support, to obtain film, placing the prepared membrane in a vacuum under oven, and drying. USE - The method is useful for preparing membranes with enhanced water flux (claimed). ADVANTAGE - The membranes with enhanced water flux has good structure stability, simple preparation process; and is suitable for high voltage; and improves separation efficiency of film, and suitable for large scale.
