Membranes for fluid separation

Membranes, methods of making the membranes, and methods of using the membranes are described herein. The membranes can comprise a gas permeable support and a continuous phase comprising a selective inorganic material disposed within the gas permeable support. In some embodiments, the membranes can exhibit a CO2:N2 selectivity of at least 10 at 24° C. The membranes can be bendable, such that when the membranes are wrapped around a 1.5-inch diameter cylinder and returned to a planar conformation, the CO2:N2 selectivity of the membranes is at least 25% of the CO2:N2 selectivity of the membranes prior to having been wrapped around the cylinder.
