CO2‐selective Pebax/NaY mixed matrix membranes (MMMs) were prepared by incorporating NaY zeolite into Pebax matrix. The morphology, chemical groups, thermal stability, and microstructure of the MMMs were investigated by scanning electron microscope, Fourier transform infrared spectroscopy, thermogravimetric analysis, and X‐ray diffraction, respectively. The effects of zeolite loading amount, permeation temperature and pressure on the CO2/N2 separation performance of the resultant membranes were studied. The as‐prepared MMMs are much superior to the pristine Pebax membranes in terms of permeability and selectivity. The CO2 permeability and CO2/N2 selectivity can respectively reach to 131.8 Barrer and 130.8 for MMMs made by the starting materials containing 40?wt % NaY.
