▎ 摘  要

NOVELTY - The method involves adding 0.5-0.1mmol of cross linking agent with 100 mg/mL of graphene oxide solution at T150 degrees Celsius for 4-8 h to obtain oxidized graphene hydrogel. A hydrogel drying process is performed for the oxidized graphene hydrogel to obtain graphene oxide. Graphene oxide dry gel is obtained. A film-pressing process is performed for the graphene oxide dry gel with pressure of 10-200 Pa for 5-50 min. A graphene oxide film reducing process is performed to obtain a graphene film. USE - Method for manufacturing an oil-water separating-type graphene film in a large-scale industry. ADVANTAGE - The method enables simplifying preparation process of a graphite alkenyl oil-water separating film so as to reduce production cost of the graphite alkenyl oil water separating film. The method enables producing the graphite alkenyl oil-water separating film in a light stable manner. The method enables improving multi-environment efficiency and ensuring low energy consumption. The method enables utilizing high-speed separating oil-water mixture to isolate oil and water in an effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view illustrating an oil-water separating-type graphene film manufacturing method.
