▎ 摘　　要

NOVELTY - Manufacture of graphene oxide framework composite film involves preparing graphene oxide suspension solution by the Hummer method, synthesizing organometallic framework (MOF) nanoparticles with functional groups, mixing the MOF nanoparticles into the graphene oxide suspension solution and dispersing ultrasonically, and heating to react to form graphene oxide-MOF framework structure suspension, and preparing the GO-MOF framework composite film by the pressure filtration method. USE - Manufacture of graphene oxide framework composite film used in membrane separation processes such as nanofiltration, pervaporation, and gas separation. ADVANTAGE - The method enables stable and simple manufacture of graphene oxide framework composite film. The size of the particle size of the MOF nanoparticles can be controlled by controlling the reaction time and temperature of the MOF nanoparticles, so that the framework structure of the graphene oxide film can be controlled and adjusted. The graphene layer spacing is flexibly adjusted during the process of preparing the graphene oxide film.
