Abstract: The invention relates to a method for producing a thermoresponsive filtration membrane, particularly a microfiltration membrane or ultra-filtration membrane, and a corresponding thermoresponsive filtration membrane. The method according to the invention comprises the following method steps: a) a filtration membrane is wetted or coated with a dopamine solution, b) the dopamine of the dopamine solution is polymerised in order to produce a polydopamine layer, and c) the polydopamine-coated filtration membrane is immersed into a coating solution with an end-functionalised poly(N-isopropylacrylamide), and the poly(N-isopropylacrylamide) is bound to the polydopamine layer.

Abstract: The invention relates to a method for producing a polymer membrane with an isoporous, active separation layer, particularly an ultrafiltration membrane or nanofiltration membrane and to a polymer membrane produced or producible according to the invention. The method comprises the following steps: producing a casting solution having at least one solvent in which at least one amphiphilic block copolymer with at least two different polymer blocks and at least one carbohydrate are dissolved, spreading out the casting solution to form a film, allowing a part of the at least one solvent near the surface to evaporate during a waiting time, precipitating a membrane by immersing the film in a precipitation bath comprising at least one non-solvent for the block copolymer.
