Superomniphobic membranes for post‐combustion CO 2 capture are introduced. Concentrated aqueous amine solutions stay on the topmost part of the membranes, providing a large liquid/CO 2 interface. Wetting of the membrane, which reduces the capture efficiency, is prevented. The CO 2 capture rates using the chemically, mechanically, and thermally stable superomniphobic membranes are enhanced by up to 40% relative to commercial membranes.
