▎ 摘　　要

NOVELTY - Preparing graphene oxide water treatment film comprises using oxidation polymerization method to grow macromolecule nano-array on the surface of graphene oxide to prepare composite; dispersing the compound in the solvent to obtain uniform dispersion; after the micro-filtration membrane surface vacuum pumping and filtering dispersion liquid, forming film, after heat treatment, hydrophobic polymer nano-array is swelled by swelling, strong cohesion to make the nano sheet generate wrinkle, to obtain the graphene oxide water treatment film capable of in-situ generating surface nano-bubble. USE - Method for preparing graphene oxide water treatment film capable of in-situ generating surface nano-bubble. ADVANTAGE - The method adopts vacuum filtration and heat treatment method to prepare membrane in a simple, cost-effective and eco-friendly manner with improved physical and chemical characteristics of the wall surface of membrane pore channel, obviously reduced fluid flow resistance, and effectively improved permeability of the membrane.
