Title:
温度応答性微多孔膜およびそれを用いてなる固体高分子電解質膜
Document Type and Number:
Japanese Patent JP6429356
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a versatile membrane material capable of being properly compatible with various coating conditions by controlling the wettability of a membrane surface and optimizing the balance between a MD (Machine Direction) strength and a TD (Transverse Direction) strength by appropriately utilizing temperature characteristics possessed by the temperature responsive membrane material.SOLUTION: A temperature responsive fine porous membrane is provided by arranging amphipathic molecule on a substrate made of polyolefin. In the temperature responsive fine porous membrane, a surface free energy of the substrate is 45 mJ/mor more at 20°C and a surface free energy is 35 mJ/mor less at 45°C. A solid polymer electrolyte membrane made by using the temperature responsive fine porous membrane is also provided.
