Abstract
The current study investigates the preparation, characterization, and gas permeation properties of novel composite membranes containing polyimide (PI), ionic liquid (IL), and zeolite (ZSM-5), focusing on the effect of zeolite. The free-standing composite membranes were prepared using the solvent casting method. The SEM images show that the interfacial voids between PI and ZSM-5 decreased with increasing IL content. The addition of IL and ZSM-5 into the PI membrane improved the thermal stability of the composite membranes. The gas permeability of the composite membranes was determined at 35 °C. The gas permeability of the PI+ZSM-5 membrane was higher than that of PI, but the gas selectivity w..
