Title:
NONWOVEN FABRIC AND ELECTROLYSIS MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2010/098400
Kind Code:
A1
Abstract:
Disclosed is a nonwoven fabric which has excellent heat resistance, excellent chemical resistance and a fine fiber diameter, and can exhibit excellent mechanical strength at the temperatures of usage environments. Also disclosed is an electrolyte membrane which has excellent dimensional stability when the electrolyte membrane absorbs water and in which the increase in resistance caused by a reinforcing material can be prevented.
Specifically disclosed is a nonwoven fabric (28) which comprises fibers (26) of an ethylene/tetrafluoroethylene copolymer having a storage elastic modulus (E') of 8 × 108 Pa or more at 25°C and a melt viscosity of more than 60 Pa·s and not more than 300 Pa·s as measured at 300°C, wherein the average fiber diameter of the fibers (26) is 0.01 to 3 μm. Also specifically disclosed is an electrolyte membrane which is reinforced by the nonwoven fabric (28).
