NOVELTY - Preparation of sulfonated reduced graphene oxide-polymer mixed matrix film comprises dispersing dried sulfonated reduced graphene oxide in organic solvent to form inorganic filler dispersion, dissolving polymer matrix membrane material in organic solvent to obtain organic film casting solution, blending inorganic filler dispersion with organic film casting solution, performing ultrasonic treatment for not greater than 1 hour for solvent defoaming treatment, using sulfonated reduced graphene oxide-polymer mixture as film casting solution, applying to the surface of ultra flat glass, forming film by heating volatile solvent and quenching stripped mixed matrix membrane material at high temperature. USE - The method is for preparation of sulfonated reduced graphene oxide-polymer mixed matrix film. ADVANTAGE - The film has excellent separation performance and long-term stability and is easy to operate.
