Abstract:
Disclosed herein is a membrane scaffold comprising a planar material having a hydrophobic surface and a functional area comprising a plurality of apertures. The apertures have a diameter of from about 80µm to about 3000µm and the rims of the apertures comprise bulges extending above and/or below the surface level of the planar material. The membrane scaffold is useful in the preparation of a composite biomimetic membrane wherein functional channel forming molecules have been incorporated in said membrane.
Abstract:
Described herein is a method of producing a hollow fiber membrane having an outside coating with a thin film composite (TFC) layer comprising a transmembrane protein, said method comprising the steps of: preparing an aqueous solution comprising a self-assembled nanostructure comprising polyalkyleneimine (PAI) and a detergent solubilized transmembrane protein and a di- or triamine, preparing an apolar solution comprising a di- or triacyl halide in an apolar organic solvent, contacting a hollow fiber membrane with the either the solution according to step a) or the solution according to step b), removing excess solution if any, contacting the hollow fiber membrane with the other solution, allowing an interfacial polymerization reaction to take place, and rinsing the hollow fiber membrane with an aqueous solvent. The hollow fiber is applicable e.g. for extracting water from the product solution.
