摘要： An asymmetric membrane. The asymmetric membrane includes a membrane wall with a first and a second porous surface and an interior situated between the surfaces; a first asymmetrical region towards the first surface; a second asymmetrical region towards the second surface; wherein the asymmetric membrane is made from a polymeric blend comprising an aromatic sulfone polymer and poly (2-oxazoline); and wherein the asymmetric membrane is in the form of a flat sheet.
