Abstract:
A carbon dioxide separation membrane includes a skin layer having a function of separating carbon dioxide from a mixed gas, wherein the skin layer contains 30 to 90% by mass of a polymer resin in which a difference between an affinity to carbon dioxide and an affinity to at least one of hydrogen and helium, the affinities are expressed as free energy ΔG (kcal mol−1), is 4.5 kcal mol−1 or more and less than 10 kcal mol−1, and from 10 to 70% by mass of an organic liquid having an affinity to carbon dioxide.
