▎ 摘　　要

NOVELTY - Graphene micro-ultrafiltration membrane is claimed. The graphene micro-ultrafiltration membrane is prepared by dissolving graphene, graphene oxide, dendritic macromolecule and high molecular polymer in a solvent to prepare casting liquid, scraping or spinning or coating casting liquid on outer surface of hollow fibers braided tube, solidifying, water washing, air-drying, glutaraldehyde cross-linking, and drying. USE - Used as graphene micro-ultrafiltration membrane. ADVANTAGE - The method: introduces hydrophilic dendritic macromolecule and graphene oxide into the graphene micro-ultrafiltration membrane, which improves the hydrophilicity of the membrane; utilizes dendritic macromolecule solution to coat graphene and graphene oxide, which makes the graphene and graphene oxide uniformly and stably dissolved in the solvent, and stably disperse in the casting film liquid; realizes cross-linking and polymerizing of the dendrimer and active groups including hydroxy and amino in graphene oxide using glutaraldehyde to improve the compatibility and stability between high molecular polymers and dendrimers, graphene oxide and graphene; and improves membrane performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene micro-ultrafiltration membrane.
