Title:
【発明の名称】ミクロポーラスフィルム
Document Type and Number:
Japanese Patent JP2001516783
Kind Code:
A
Abstract:
A microporous, hydrophilic polymer film has a morphology composed of distinctively interconnected pores, which are desirably surface-open. In particular aspects, the film can provide for a water vapor transmission rate (WVTR) value of at least about 1000 grams per square meter per 24 hours per mil (0.00254 cm) of film thickness. The film can exhibit a modulus of not less than about 1 MPa, and may also exhibit an elongation strain at break of at least about 100% in both its machine and transverse directions. The film can also provide for a water contact angle of not more than about 80 degrees. In other aspects, the porous film can also include other properties or characteristics, such as a desired tensile strength at break, a desired elongation-at-break, and voids or pores having distinctive shapes, sizes, distributions and configurations.
