Title:
GAS SEPARATION MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2013/031621
Kind Code:
A1
Abstract:
[Problem] To provide a gas separation membrane which has practical mechanical strength, while having excellent gas separation performance, namely improved gas permeability coefficient that is an index for permeability of a gas and improved separation coefficient that is a ratio between gas permeability coefficients of two kinds of gases, said ratio being presented as a selectivity index between the two kinds of gases.
[Solution] A cured product of a composition which contains a monomer or oligomer having an oxyethylene chain and amorphous organic group-containing metal oxide particles is used as a gas separation membrane. It is preferable that the composition additionally contains a monomer or oligomer which has a functional group containing oxygen or nitrogen.
