▎ 摘  要

NOVELTY - The method involves fully mixing polyvinylidene fluoride (PVDF), graphene oxide, polyvinyl pyrrolidone (PVP) and organic solvent to form membrane casting solution. The formed membrane casting solution is prepared through a film forming device to prepare a hollow fiber membrane. An outlet ring of a casting channel is set on an outer side of a central channel. The central channel is filled with core liquid. Casting film liquid is compounded on a periphery of the core liquid through a casting film channel. A rinsing tank is provided with rinsing solution. A rewinding device is provided with a rewinding roller. USE - Method for preparing a graphene oxide functional modified film. ADVANTAGE - The method enables preparing the graphene oxide functional modified film in simple and cost-effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene oxide functional modified film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating a method for preparing a graphene oxide functional modified film.
