METHOD FOR PRODUCING GAS SEPARATION COMPOSITE MEMBRANE, LIQUID COMPOSITION, GAS SEPARATION COMPOSITE MEMBRANE, GAS SEPARATION MODULE, GAS SEPARATION APPARATUS, AND GAS SEPARATION METHOD

摘要

The method for producing a gas separation composite membrane includes applying a mixed liquid containing compounds (a) and (b) below onto a porous support to form a coating film and curing the coating film to form a crosslinked polysiloxane compound layer:(a) a particular crosslinkable polysiloxane compound having a structural unit (a1), a structural unit (a2), and a structural unit (a3) or (a4), and(b) a particular crosslinkable polysiloxane compound having a structural unit (b1), a structural unit (b2), and a structural unit (b3) or (b4),; ;where R^1a to R^1f and R^2a to R^2f represent a particular group and * represents a particular linking site.
