▎ 摘  要

NOVELTY - Producing continuous graphene oxide thin film comprises (a) dispersing deoxygenated graphene oxide in a mixed solvent of water and polar volatile solvent to prepare a graphene solution; and (b) coating the graphene solution on a substrate by injecting the graphene solution into a slot-die coater. USE - The method is useful for producing continuous graphene oxide thin film. ADVANTAGE - The method produces high-quality continuous graphene oxide thin film having excellent structural stability in water and high pressure and excellent filtration properties in an easy manner using slot-die coater in a large area.
