▎ 摘  要

NOVELTY - The method involves carrying out an oxidation process to obtain an oxidation graphite by peeling-off oxidation graphene. An oxidation graphene solution capsule is formed by dissolving the oxidation graphene solution in water. The oxidation graphene solution is mixed with polyethylene alcohol solution by a porous carrier to perform cleaning and surface treatment. An oxidation graphene film is formed on a surface of the porous carrier, where the porous carrier is provided with a porous ceramic and porous stainless steel. USE - Graphene oxide film preparation method. ADVANTAGE - The method enables utilizing cheap graphite material to prepare an oxidation graphene composite film with high selectivity and permeation flux through water, effectively separating azeotrope from water to purify water containing azeotrope and adopting eco-friendly environment. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic illustration of a graphene oxide film preparation method.
