%X Zeolite A/poly (1-trimethylsilyl-1-propyne) (zeoliteA/PTMSP) and [emim][Ac]/chitosan (IL/CS) are mixed-matrix membrane (MMM) materials with enhanced CO2/N2 permselectivity even at higher temperature. The scalability to asymmetric flat and hollow-fiber geometry by a simple dip-coating method was analyzed. The CO2/N2 separation performance was evaluated at different temperatures. The resulting composite membranes exhibit a significantly enhanced CO2 permeation flux because the MMM layer thickness is reduced by 97 % from flat to hollow-fiber geometries in IL-CS composite membranes, while the selectivity is maintained similar to the self-standing membranes, thus proving that compatibility between the membrane component materials leads to a defect-free composite membrane, regardless the geometry and temperature.
