NOVELTY - Super-hydrophilic graphene flat-plate microporous filter membrane includes 10-20 pts. wt. hydrophilic microporous filter film, 0.1-0.5 pts. wt. graphene, 0.1-0.5 pts. wt. additive and 0.1-0.5 pts. wt. additive. USE - Super-hydrophilic graphene flat microporous filter film. ADVANTAGE - The super-hydrophilic graphene flat microporous filtering film is prepared with high hydrophilicity, and the graphene and homopolymer are compatible, solves the problem that the graphene is easy to separate in the application. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of a super-hydrophilic graphene flat microporous filter membrane, which involves: (A) mixing solid polymer homopolymer, organic solvent, hydrophilic polymer and non-organic solvent additives, stirring, and dissolving to a uniform state at a temperature of 40-120 degrees C in a water bath; (B) adding a certain amount of graphene to the solution, and obtaining a casting solution after further stirring; (C) preparing the casting liquid into a nascent ecological film; (D) placing the nascent film in water at 20-70 degrees C to solidify into a film; and (E) washing the membrane solidified with water and alcohol in order, and then drying to obtain a super-hydrophilic graphene flat microporous filter membrane.
