Document Type and Number:
Japanese Patent JP7313114
Kind Code:
B2
Abstract:
To provide a composite membrane preventing a part without becoming a membrane from existing, and useful for various industrial applications because of having extremely thin membrane structure part with uniform thickness.SOLUTION: There is provided a composite membrane having a membrane structure part which has a first fiber layer and a second fiber layer, and a membrane constitutional resin existing between constitution fibers of the first fiber layer, average fiber diameter of the fiber constituting the first fiber layer is 3 μm or less, and further a part without becoming a membrane is prevented from existing only when a combination that the first fiber layer has lower hydrophilicity than the second fiber layer is satisfied, and for example a composite membrane having extremely thin membrane structure part having membrane thickness of 10 μm or less with uniform thickness can be provided.SELECTED DRAWING: Figure 1
