ABSTRACT:
A hydrophilized porous film which can be obtained through hydrophilizing by a simple method without impairing rejection performance and permeation performance and easily retains the properties of a film material, and to provide a process for producing the same. The hydrophilized porous film comprises a hydrophobic polymer and dispersed therein an organized clay which has been organized with a hydrophilic compound, and is obtained by a process including a step of dispersing a clay organized with a hydrophilic compound in a solution of a hydrophobic polymer and a step of subjecting this solution to phase separation to obtain the hydrophilized porous film.
