▎ 摘  要

NOVELTY - Graphene oxide polymer nanofiber multilayer film comprises greater than or equal to 2 layers of polymer nanofiber film and graphene oxide film layer, which are alternately arranged, where graphene oxide is at 50-80 wt.%. USE - Graphene oxide polymer nanofiber multilayer film used for air filtration, sewage treatment and desalination membrane separation field (all claimed). ADVANTAGE - The graphene oxide polymer nanofiber multilayer film has graphene oxide high load capacity, high mechanical strength, good stability, pure water flux and good nanofiltration performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene oxide polymer nanofiber multilayer film comprising electrospinning a layer of polymer to prepare polymer nanofiber film, electrostatic spraying graphene oxide on polymer nanofiber film uniformly, electrospinning polymer nanofiber film on graphene oxide film layer, and repeating the steps to obtain graphene oxide film layer and polymer nanofiber film layer, which are alternately arranged to form multilayer film.
