NOVELTY - Preparation of super-hydrophilic graphene filter membrane comprises adding graphite oxide in organic solvent, using cell crusher for ultrasonic oscillation to obtain graphene oxide solution, adding film-forming material and stirring to obtain graphene oxide solution of film-forming material, adding crosslinking agent and pore-opening agent, heating and stirring to obtain polymer solution, filtering polymer solution, filtering again the filtrate and washing for 2 times, and vacuum heating and drying. USE - The super-hydrophilic graphene filter membrane is used for dynamic separation of oil-water emulsion. ADVANTAGE - The graphene oxide enhances hydrophilicity and mechanical strength of the high molecular polymer after doping. The filter membrane has characteristic of anti-pollution, and separates with high efficiency.
