OXYGEN PERMEABLE FILM, OXYGEN PERMEABLE SHEET, AND CELL INCLUDING THESE |
摘要 |
An oxygen permeable film including an aggregate of water-repellent particles and having an average particle size of the particles of 0.01 to 50 mum has a contact angle with water of not less than 120° and super water repellency, and therefore has an excellent water vapor permeation inhibiting capability. As the particles, fluorocarbon resins such as polytetrafluoroethylene, polyvinyl fluoride and polyvinylidene fluoride are suitable. The specific surface area of the oxygen permeable film is preferably not less than 0.1 m2/g and not more than 500 m2/g.
