▎ 摘　　要

NOVELTY - A halloysite nanotube/graphene oxide oil-water separation membrane comprises nylon bottom film as a support layer and having a thickness of 300-700 nm, and halloysite nanotube/graphene oxide layer loaded on nylon bottom film, in which halloysite nanotubes are randomly distributed between graphene oxide sheets to form an intercalation structure. USE - Halloysite nanotube/graphene oxide oil-water separation membrane used for treating marine oil spills and domestic sewage (all claimed). ADVANTAGE - The oil-water separation membrane has high water flux, separation efficiency, and overcomes the defect of easy fouling of oil-water separation membranes, low separation efficiency, and reusable problem. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the halloysite nanotube/graphene oxide oil-water separation membrane.
