| titleOfInvention | process of interfacial polymerization to form a thin-film composite membrane |
| abstract | thin film composite membrane for gas separation or liquid filtration, and interfacial polymerization process to form a thin film composite membrane. the present invention relates to a composite membrane for the separation of gases and / or nanofiltration from a solution of a feed stream solution comprising a solvent and dissolved solutes and showing preferential rejection of the solutes. the composite membrane comprises a separation layer with intrinsic microporosity. the separating layer is suitably formed by interfacial polymerization on a support membrane. appropriately, at least one of the monomers used in the interfacial polymerization reaction must have a concavity, resulting in a network polymer with interconnected nanopores and a membrane with increased permeability. the support membrane can optionally be impregnated with a conditioning agent, and can be optionally stable in organic solvents, particularly in polar aprotic solvents. the top layer of the composite membrane is optionally terminated with functional groups to change the surface chemistry. the composite membrane can be cured in the oven to improve rejection. finally, the composite membrane can be treated with an activating solvent before nanofiltration. |
