▎ 摘  要

NOVELTY - Preparing non-layered graphene oxide crosslinked film, comprises (i) mixing polyhydric ammonia or terminal amino polymer with graphene oxide aqueous dispersion, and evenly dispersing to form graphene oxide sol; (ii) dropwise adding the graphene oxide sol onto a substrate, placing at 70-90 degrees C and sealing. USE - The non-layered graphene oxide crosslinked film is useful for oil-water separator (claimed). ADVANTAGE - The non-layered graphene oxide crosslinked film has superhydrophilic and oleophobic properties underwater, high flux and good anti-pollution performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for non-layered graphene oxide crosslinked film, prepared as mentioned above.
