| titleOfInvention | Method for producing hydrophilic porous membrane |
| abstract | Provided is a method for producing a hydrophilic porous membrane that includes a porous film and a hydrophilizing coating, where the hydrophilizing coating covers at least part of the outer surface of the porous film. The method comprises impregnating the porous membrane with a hydrophilizing liquid for forming the hydrophilizing coating and curing the porous membrane that has been impregnated with the hydrophilizing liquid by a curing reaction. The hydrophilizing liquid contains a polymerizable monomer and a mixed solvent of a polar organic solvent and water. The total mass of the polar organic solvent in relation to the total mass of the mixed solvent is 10-60 mass%. The curing reaction is performed by irradiating, with light, a region of the porous membrane which is entirely impregnated with the hydrophilizing liquid in the thickness direction and the mass of which becomes 3-16 times the mass of the porous membrane in an unimpregnated state. With this production method according to the present invention, a hydrophilic porous membrane which has high hydrophilicity and maintains water permeability and wettability even after high-pressure steam sterilization can be produced. |
