Global warming is a public alarming issue caused by extreme CO2 emissions. Thus, CO2 removing using thin film nanocomposite (TFN) membranes is an efficient procedure to enhance the CO2 gas separation efficiency. TFN membranes composed of Pebax 1657 embedded by porous organic polymers over the porous polysulfone support used to separate CO2 from CH4 and N2 gases. Porous organic polymers (POPs) were synthesized via Friedel-Crafts one-step reaction. The obtained results from TGA and FESEM revealed that the modified TFN membranes declared a superior compatibility between Pebax and fillers. Permeation properties of membrane samples were tested over various feed pressure with the range of 2-10 bar. Pure gases permeability, CO2/N2 and CO2/CH4 selectivities improved via adding porous organic polymers into the Pebax. At porous organic polymers loading of 5wt% and applied feed pressure of 2 bar, the CO2, CH4 and N2 permeability enhanced to 310.6, 27.6 and 4.5 Barrer, respectively; which exhibited a significant improvement compared to neat membrane. Moreover, the CO2/N2 and CO2/CH4 selectivities also enhanced to 11.25 and 70.04; respectively. Obtained results revealed that the membranes performance was enhanced as the feed gas pressure increased. TFN containing 5wt% porous organic polymers imply a CO2 gas permeability of 348.4 Barrer at feed pressure of 10 bar.
