| titleOfInvention | Preparation method of composite membrane material capable of efficiently separating gas |
| abstract | The invention relates to a composite membrane material capable of efficiently separating gas and a preparation method thereof, wherein a composite material CMP @ Polymer of a conjugated microporous Polymer and an organic Polymer is prepared in two solutions by a continuous liquid phase impregnation method; using organic polymer as a substrate, dipping the substrate into a solvent I in advance, then dipping the substrate into a solvent II, and repeating the operation until an effective membrane material is synthesized; soaking and washing the composite membrane material in water, ethyl acetate and ethanol, repeatedly soaking and washing, and drying; one of the two solutions is prepared by a sulfonate compound and a solvent I, and the other solution is prepared by an aldehyde aromatic compound, an amino aromatic compound and an organic solvent II; the composite membrane material is synthesized by a continuous liquid phase impregnation method, the method has universality, simple operation, low raw material cost and large-scale processability, and the gas flux and selectivity of the composite membrane material can be regulated and controlled by controlling the concentration of reactants, the continuous impregnation times and the impregnation time. |
