Abstract
A gas separation composite membrane, containing a gas-permeable supporting layer and a gas separating layer containing a crosslinked polyimide resin over the gas-permeable supporting layer, in which the crosslinked polyimide resin is formed by a polyimide compound being crosslinked by a radically crosslinkable functional group thereof, and a ratio [η] of a crosslinked site to an imide group of the polyimide compound (the number of crosslinked sites/the number of imide groups) in the crosslinked polyimide resin is 0.0001 or more and 0.45 or less; a method of producing the same; and a gas separating module, a gas separation apparatus and a gas separation method using the same.
