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.
