▎ 摘　　要

NOVELTY - A layered molybdenum disulfide nanosheet blended and reduced graphene oxide nanofiltration membrane comprises support layer and separation layer. The supporting layer is a polyvinylidene fluoride porous bottom film, and separation layer is a layered molybdenum disulfide nanosheet blended and reduced graphene oxide separating film. USE - The layered molybdenum disulfide nanosheet blended and reduced graphene oxide nanofiltration membrane used for organic dye-water system separation (claimed). ADVANTAGE - Thes method solves the problem of low water flux caused by the small separation membrane layer spacing, effectively improve the water flux and selectivity of nanofiltration membranes, and have broad application prospects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of layered molybdenum disulfide nanosheet blended and reduced graphene oxide nanofiltration membrane comprising adding molybdenum disulfide powder and liquid-phase ultrasonic intercalant to the organic dispersant, stirring and ultrasonicating, standing, centrifuging, taking supernatant and centrifuging again, discarding supernatant, adding organic dispersant, repeating centrifugation to obtain molybdenum disulfide precipitate, adding organic dispersant, ultrasonicating to obtain molybdenum disulfide dispersion, mixing with reduced graphene oxide dispersion, ultrasonicating to obtain mixed dispersion, filtering onto polyvinylidene fluoride porous bottom membrane, and drying.
