▎ 摘　　要

NOVELTY - A graphene oxide membrane dehydration performance enhancing method involves preparing graphene oxide film by preparing support surface graphene oxide ceramic or organic composite film, drying, allowing to stand, preparing modifier by dissolving hydrophilic polymer in solvent, heating, stirring and allowing ultrasonic treatment obtain a uniform dispersion of the modifier solution. The modifier solution is coated on the graphene oxide film surface, and dried. USE - Method for enhancing dehydration performance of graphene oxide membrane. ADVANTAGE - The method enables enhancing dehydration performance in simple and easy manner.
