  • Publication number: 20180022846
    Abstract: The invention provides a hydrophilizing agent which is to be added to a polymer having a large contact angle to produce a porous polymer film that has a small contact angle and that can maintain this small contact angle even after 168-hour contact with an aqueous sodium hypochlorite solution. The hydrophilizing agent contains a fluoropolymer having a contact angle of 50° or smaller and a weight reduction rate of 7% or lower.
