| titleOfInvention | Membranes for separation |
| abstract | The present invention relates to a composite membrane for gas separation and / or nanofiltration of a feed stream solution comprising a solvent and a dissolved solute, wherein the composite membrane exhibits a desirable solute rejection rate. The composite membrane includes an isolation layer having an inherent microporosity. The separation layer is suitably formed by interfacial polymerization on the support film. Suitably, the one or more monomers used in the interfacial polymerization reaction should have a recess to produce a network polymer with interconnected nanopores and a film with enhanced permeability. The support membrane may optionally be impregnated with a conditioning agent and may optionally be stable in an organic solvent, especially in a polar aprotic solvent. The top layer of the composite membrane may optionally be capped with functional groups to alter the interfacial chemistry. The composite membrane may be cured in an oven to improve rejection. Finally, the composite membrane may be treated with an activating solvent prior to nanofiltration. |
