▎ 摘　　要

NOVELTY - Preparing graphene oxide-metal-organic framework (GO-MOF) modified polyvinylidene fluoride flat membrane, comprises (a) dissolving GO-MOF in solvent, adding hydrophilic components and additives, and adding polyvinylidene fluoride resin to prepare uniform and stable casting solution, where the content of GO-MOF is 0.5-6 wt.%, the content of polyvinylidene fluoride resin is 10-25 wt.% and the content of the hydrophilic component in the casting solution is 0.5-5.5 wt.%; and (b) casting the casting liquid on the support layer, scraping the support layer immersed in the casting liquid, and allowing to stand in the air for 10-400 seconds, take out after passing through the first coagulation bath, the second coagulation bath and the third coagulation bath in sequence, and drying the membrane. USE - The flat membrane is useful in the preparation of the membrane bioreactor process membrane (claimed). ADVANTAGE - The GO-MOF modified polyvinylidene fluoride flat membrane has high porosity, high permeability and high selectivity, and has great potential in the high-efficiency membrane separation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene oxide-metal-organic framework modified polyvinylidene fluoride flat membrane.
