<p>Membrane element (10, 50) for selective transport of one or more compounds, comprising a polymeric membrane layer (12, 13) and a support (11). The polymeric membrane layer (12, 3) is operable for selectively transporting the one or more compounds through the membrane layer and comprises a first polymer compound. The support (11) has a thickness of at least 200 µm and comprises a support layer (111, 112) enabling the one or more compounds to permeate through the support layer, wherein the support layer comprises a second polymer compound. The membrane layer (12, 13) is obtained by application of a solution of the first polymer compound on the support layer (111, 112) and forming the membrane layer through phase separation of the first polymer compound from the solution, wherein the membrane layer and the support layer share an interface. The first and second polymer compounds are such that the membrane layer is solvent bonded to the support layer through molecular interaction between the first and second polymer compounds at the interface when the membrane layer is formed.</p> |
