COMPOSITE MEMBRANE WITH SUPPORT COMPRISING POLY(PHENYLENE ETHER) AND AMPHILPHILIC POLYMER; METHOD OF MAKING; AND SEPARATION MODULE THEREOF |
摘要 |
A porous composite membrane includes a porous support layer of a poly(phenylene ether) or poly(phenylene ether) copolymer; and an amphiphilic copolymer having a hydrophobic block and a hydrophilic block or graft, wherein the hydrophobic block includes a polystyrene block, a poly(phenylene ether) block, or a poly(phenylene ether) copolymer block; and an ultrathin, cross-linked, water permeable layer, which is the reaction product of an electrophilic monomer and a nucleophilic monomer, in contact with a side of the porous support layer. The reaction product can be a polyamide that is the interfacial condensation product of: an aromatic, polyfunctional acyl halide comprising of 3 to 6 acyl halide groups per aromatic ring and an aromatic polyamine comprising at least two primary amine groups and a maximum number of primary amine groups that is less than or equal to the number of acyl halide groups on the polyfunctional acyl halide. |

1. A porous composite membrane comprising:
a porous support layer comprising, consisting essentially of, or consisting of a hydrophobic polymer comprising, consisting essentially of, or consisting of a poly(phenylene ether) or poly(phenylene ether) copolymer; and an amphiphilic copolymer comprising a hydrophobic block and a hydrophilic block or graft wherein the hydrophobic block comprises a polystyrene block, a poly(phenylene ether) block or a poly(phenylene ether) copolymer block; and an ultrathin, cross-linked, water permeable layer in contact with a side of the porous support layer, and comprising the reaction product of an electrophilic monomer and a nucleophilic monomer. |
