Document Type and Number:
WIPO Patent Application WO/2021/193667
Kind Code:
A1
Abstract:
The present invention provides a gas sealing member for high-pressure hydrogen devices, said gas sealing member being capable of sufficiently suppressing the occurrence of a blister rupture, while having excellent durability. A gas sealing member for high-pressure hydrogen devices according to the present invention is formed of a crosslinked product of an elastomer composition that contains an elastomer and fibrous carbon nanostructures that have an average length of from 100 μm to 1,000 μm. The fibrous carbon nanostructures have a surface fractal dimension of from 2.3 to 3.0, or a radius of gyration of from 50 nm to 500 nm, while having an inner diameter of 4.0 nm or less.
