摘要： PROBLEM TO BE SOLVED: To provide a composite porous membrane that is excellent not only in filtration performance but also in adhesion between a filter medium and a supporter and has excellent mechanical properties.
SOLUTION: The composite porous membrane is prepared by forming a first porous layer having a dense layer and forming a second porous layer having a dense layer adjacent to the first porous layer on the surface of a supporter. The composite porous membrane having the polyol impregnation ratio of 50-100% is excellent in mechanical properties such as adhesion strength between the filter medium and the supporter. Therefore, it is usable under severe conditions such as applications of various types of water treatments to enhance the quality of the filtrate. Also, since the penetration performance are high, the membrane area to be used is getting smaller, thereby compacting the equipment.
