SKINNED, ASYMMETRIC POLY(PHENYLENE ETHER) CO-POLYMER MEMBRANE; GAS SEPARATION UNIT, AND PREPARATION METHOD THEREOF |
摘要 |
An asymmetric membrane having a substantially non-porous surface layer is made by a method including: dissolving a poly(phenylene ether) copolymer in a solvent mixture including a first solvent and a second solvent to provide a membrane-forming composition; and phase-inverting the membrane forming composition in a first non-solvent to form the membrane comprising a substantially non-porous surface layer. The first solvent is a water-miscible polar aprotic solvent, and the second solvent is a polar solvent having two to eight carbon atoms. |
