▎ 摘　　要

NOVELTY - Preparing graphene oxide nanofiltration membrane hybridized with polypyrrole microspheres, comprises inserting polypyrrole nanospheres into graphene oxide nanofiltration membranes as intercalation agents to obtain polypyrrole/graphene oxide hybrid film, where the particle diameter of polypyrrole nanospheres is 180-220 nm. USE - The method is useful for preparing graphene oxide nanofiltration membrane hybridized with polypyrrole microspheres. ADVANTAGE - The method improves the ability of water molecules to transport; has strong interaction with graphene oxide nanosheets; and enhances the mechanical stability of the hybrid membrane. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene oxide nanofiltration membrane hybridized with polypyrrole microspheres prepared as mentioned above, where hydration diameter used for the extended interception treatment is less than graphene oxide nanofiltration dye molecules with interlayer spacing.
