N2  - A combination of organic filler exhibiting CO2 philic nature with a polymer to develop mixed matrix membranes (MMMs) can capture CO2 efficiently. This work reports the synthesis of perylene filler and polysulfone (PSf)-based MMMs via solution casting method. The successful incorporation of fillers, uniformity/asymmetric, and amorphous nature of MMMs were investigated by FT-IR, FESEM, and PXRD analysis, respectively. MMMs demonstrated high thermal stability with significant weight retention over 750 °C investigated by TGA analysis. The existence of Lewis's basic functionalities, hydrogen bonding, and Ï?-Ï? bonds between the filler-polymer resulted in the formation of highly CO2 philic structure. Results revealed that the perylene is found to be highly porous (1050 m2/g) and compatible with the PSf to form additional channels, enhancement of free PSf volume and tendency to prevent the agglomeration and non-selective interfacial voids. It demonstrated improved permeabilities of CO2 (138), CH4 (59), and N2 (60) without any significant variation in selectivities CO2/CH4 (3) and CO2/CH4 (7). Similarly, mixed gas permeabilities were improved for (CO2â??CH4 â?? 119) and (CO2â??N2 â?? 116) along with enhanced selectivities (CO2â??CH4 â?? 50) and (CO2â??N2 â?? 46). Furthermore, the influence of temperature on gas permeabilities revealed improved kinetic energy and flexibility in the polymer chains. The mechanical strength analysis revealed high filler-polymer compatibility. These results revealed great potential of MMMs for efficient CO2 separation from pre- and post-combustion sources. © 2019 Elsevier B.V.
