▎ 摘　　要

NOVELTY - A zwitterions functionalized graphene oxide-based separation membrane comprises a separation layer and a support layer, where the membrane layer after the polymer solution and the functionalized graphene oxide solution are alternately spin-coated is utilized as the separation layer, and the polymer ultrafiltration membrane is utilized as the support layer. USE - Zwitterions functionalized graphene oxide-based separation membrane. ADVANTAGE - The zwitterions functionalized graphene oxide-based separation membrane can be prepared with stable membrane structure, better water selective separation, high flux, high separation selectivity and wide application prospect, and better effect of ensuring the stability of the film structure and improving the separating efficiency of the film, in simple and cost-effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing zwitterions functionalized graphene oxide-based separation membrane.
