▎ 摘　　要

NOVELTY - Preparation of hybrid graphene oxide material involves mixing graphene oxide aqueous dispersion and composite nanosphere aqueous dispersion to obtain uniform and stable hybrid graphene oxide dispersion of composite nanospheres, and preparing a composite nanosphere hybrid graphene oxide material. The composite nanosphere aqueous dispersion is prepared by dispersing layered double hydroxide-coated carbon nanotube microspheres (A) and highly ordered titanium dioxide microspheres (B) in water. USE - Preparation of hybrid graphene oxide material used for preparing nanofiltration membrane for filtering dye (all claimed) in textile, medicine, rubber and chemical industries. ADVANTAGE - The method enables to prepare hybrid graphene oxide material that enhances the mechanical property of the oxidation graphite and maintains the stable water flux and dye retention rate while maintaining the high-efficiency separation of the nano-filtration membrane. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a nanofiltration membrane.
