▎ 摘　　要

NOVELTY - A high-flux graphene oxide quantum dot composite nanofiltration membrane by dopamine-assisted deposition is prepared by utilizing polyacrylonitrile ultrafiltration membrane as substrate base membrane, performing carboxylation modification using alkali solution, immersing in dopamine solution, modifying to form polydopamine layer, immersing in graphene oxide quantum dot solution, depositing graphene oxide quantum dot layer, adding crosslinking agent solution, and performing in-situ crosslinking. USE - A method for preparing high-flux graphene oxide quantum dot composite nanofiltration membrane. ADVANTAGE - The product has simple preparation method and has good operation stability.
