Abstract:
A porosity is freely controlled in preparation of a porous polymer film by a phase separation method. A solvent absorption sheet is used for a solvent in a polymer solution so that the coating film of the polymer solution may be covered with the sheet. After that, the solvent in the film is selectively removed. Then, the resultant is immersed in a poor solvent. Thus, a porous polymer film can be produced.
