LIQUID SEPARATION MEMBRANE AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2022/113604

A1

The present invention provides a liquid separation membrane having an exceptional effect for suppressing fouling of the membrane, and a method for producing the liquid separation membrane.　This liquid separation membrane (1) has a substrate (6) having a porous layer (2) that has an average pore diameter of 0.1 nm to 100 μm, and a coating layer (4) that coats at least part of the surface of the substrate (6) and that contains an oleophobic polymer. Moreover, in this method for producing a liquid separation membrane, at least part of the surface of a substrate having a porous layer that has an average pore diameter of 0.1 nm to 100 μm is coated with an application liquid containing an oleophobic polymer and a solvent, the solvent is subsequently removed, and an oleophobic polymer layer is formed.
