摘要： The present invention relates to a process for preparing an asymmetric integrally skinned membrane for the separation of at least one solute from a solution, comprising the steps of: (a) preparing a polybenzimidazole dope solution comprising: (i) a polybenzimidazole polymer, and (ii) a solvent system for said polybenzimidazole which is water miscible; (b) casting a film of said dope solution onto a support; (c) immersing the film cast on the support into a coagulating medium to form an asymmetric integrally skinned membrane; (d) treating the membrane from step (c) with a cross-linking agent; (e) treating the membrane from step (d) with a cross-link modification agent. Further aspects relate to an asymmetric integrally skinned membrane and uses thereof.

摘要： A process for preparing non-naturally-occurring defined monomer sequence polymers is provided, and in which a high degree of synthetic control is obtained by the use of solvent resistant diafiltration membranes. Also provided is a process for separating non-naturally-occurring defined monomer sequence polymers from synthetic by-products or excess reagents using solvent resistant diafiltration membranes, and a use of a solvent resistant diafiltration membrane in processes for preparing and separating non-naturally-occurring defined monomer sequence polymers.

摘要： The present invention relates to a composite membrane for nanofiltration of a feed stream solution comprising a solvent and dissolved solutes and showing preferential rejection of the solutes. The composite membrane comprises a thin polymeric film formed by interfacial polymerization on a support membrane. The support membrane is further impregnated with a conditioning agent and is stable in polar aprotic solvents. The composite membrane is optionally treated in a quenching medium, where the interfacial polymerization reaction can be quenched and, in certain embodiments, membrane chemistry can be modified. Finally the composite membrane is treated with an activating solvent prior to nanofiltration.

摘要： 2-dimensional carbon thin films are described, as well as their processes of preparation, and their specific uses. The 2-dimensional carbon thin films are fabricated by preparing an organic polymeric thin film precursor, which is then subjected to a carbonisation process to remove at least some of the non-carbon atoms. Using the disclosed process, 2-dimensional carbon thin films having improved dimensional characteristics can be reliably prepared, which presents clear advantages in applications which have until now been restricted to the use of 2-dimensional carbon thin films having less useful dimensions.

摘要： The present invention relates to a composite membrane for gas separation and/or nanofiltration of a feed stream solution comprising a solvent and dissolved solutes and showing preferential rejection of the solutes. The composite membrane comprises a separating layer with intrinsic microporosity. The separating layer is suitably formed by interfacial polymerisation on a support membrane. Suitably, at least one of the monomers used in the interfacial polymerisation reaction should possess concavity, resulting in a network polymer with interconnected nanopores and a membrane with enhanced permeability. The support membrane may be optionally impregnated with a conditioning agent and may be optionally stable in organic solvents, particularly in polar aprotic solvents. The top layer of the composite membrane is optionally capped with functional groups to change the surface chemistry. The composite membrane may be cured in the oven to enhance rejection. Finally, the composite membrane may be treated with an activating solvent prior to nanofiltration.
