▎ 摘 要
NOVELTY - Preparing three-dimensional porous graphene functionalized assembly film material involves dispersing fumed graphene into deionized water to form an oxidized graphene dispersion at a concentration of 2 mg/ml, and adjusting the pH 8.5 by adding tris-hydrogen chloride buffer (Tric-HCL). The carbon nanotubes are then added to an oxidized graphene dispersion and subjected to ultrasonic dispersion in an ice-water bath at 0-5 degrees C in a mass ratio of 10:1-1:2, and then the mass ratio of the graphene and carbon nano-tubes is 10 dispersion hydrothermal reaction. USE - Method for preparing three-dimensional porous graphene functionalized assembly film material used for preparing membrane for oil-water separation (claimed). ADVANTAGE - The method enables to prepare three-dimensional porous graphene functionalized assembly film material, which has high-flux fast separating effect, and is hydrophilic. DETAILED DESCRIPTION - Preparing three-dimensional porous graphene functionalized assembly film material involves dispersing fumed graphene into deionized water to form an oxidized graphene dispersion at a concentration of 2 mg/ml, and adjusting the pH 8.5 by adding tris-hydrogen chloride buffer (Tric-HCL). The carbon nanotubes are then added to an oxidized graphene dispersion and subjected to ultrasonic dispersion in an ice-water bath at 0-5 degrees C in a mass ratio of 10:1-1:2, and then the mass ratio of the graphene and carbon nano-tubes is 10 dispersion hydrothermal reaction. The product of three-dimensionally assembled by natural cooling to room temperature, and then freeze-dried to obtain three-dimensional self-assembled graphene-carbon nano-tube composites. The graphene-carbon nano-tube composite material dispersed in water to prepare a mixed dispersion, in which the addition of dopamine ultrasonic dispersion, prepared into 1-3 mg/ml graphene and 0.5-1.5 mg/mL dopamine mixture. The mixture is mixed at 70-90 degrees C under hydrothermal reaction for 10-14 hours, the reaction after the end of natural cooling to room temperature. The black cylindrical polytepamine functionalized carbon nano-tube-graphene hydrogel column, freeze-dried polytamine functionalized carbon nanotube-graphene hydrogel column into ultra-light porous gypsum gel. The ultra-light porous gypsum airgel into small pieces and then adding to the N,N-dihydroxyethylglycine for ultrasonic dispersion, and mixed with N,N-dihydroxyethylglycine solution dissolved in the thermosensitive polymer. The reaction is carried out at room temperature for 48 hours, and the thermal reaction film is prepared by vacuum suction filtration. The thermosensitive polymer is poly 2-propenoic acid, 2-methyl-,2-(2-methoxyethoxy)ethyl ester, P (OEMO2-MA), and the ultra-light porous graphene. The mass ratio of gel to thermosensitive polymer is 1:1.
