Karbon dioksida (CO2) adalah penyumbang utama kepada kesan rumah hijau sejak revolusi perindustrian. Cecair Ionik (ILs) telah diperkenalkan secara meluas dalam era globalisasi ini kerana IL mempunyai kebolehtepan dan kelarutan CO2 yang tinggi. dan secra tidak langsung dapat meningkatkan prestasi pemisahan CO2. Dalam kajian ini, imdazolium-cecair ionik telah digunakan untuk meningkatkan and memperbaiki di antara muka polysulfone (PSf) dengan SAPO-34 zeolit dalam asimetri matriks campuran membrane (MMM) yang telah disediakan dengan kaedah penyongsangan fasa bagi mengurangkan rintangan pemindahan jisim. PSf/SAPO-34 MMMs telah diubahsuai dengan merendamkan membrannya dalam IL larutan (1-Etil-3 Metilimidazoliumbis Trifluoromethysulfonyl) Imide). Objectif utama kajian ini adalah untuk mengkaji kesan kepekatan IL pada membran dan prestasi pemisahan CO2. Morfologi pengubasuain IL dengan menggunakan mikroskop elektron pengimbas (SEM) membuktikan penyebaran telaga daripada SAPO-34 tertakluk kepada meningkatkan polimer / antara muka pengisi. Fourier mengubah spektrum inframerah (FTIR) juga mengesahkan bahawa IL telah berjaya dilarutkan ke dalam MMM dan direkodkan untuk menyemak bon kewujudan dalam sampel membran. Membran dengan pengubasuian IL telah dapat meningkatkan kenalan di antara muka polimer dengan zeolite. Kelarutan CO2, pemilihan CO2/N2 dan CO2/CH4 muka kedap yang menggunakan 0.2M MMM IL telah dipertingkatkan, dikenai 319.73%, 601.69% dan 605.84% lebih tinggi daripada MMMs. _______________________________________________________________________________________________________ Carbon dioxide (CO2) is the main contributor to greenhouse effect since industrial revolution. Ionic liquids (ILs) have been extensively studied in the recent years to improve the performance of CO2 separation due to the high CO2 solubility and selectivity. In this study, imidazolium-based ionic liquid was used to improve and functionalise the interface between polysulfone (PSf) and SAPO-34 zeolite in the asymmetric mixed matrix membrane (MMM) which was prepared by phase inversion method for minimum mass transfer resistance. PSf/SAPO-34 MMMs were post-modified by immersing the membranes into IL solution (1-Ethyl-3 Methylimidazoliumbis (Trifluoromethysulfonyl) Imide). The main objective of this work is to study the effects of IL concentration on the membrane morphology and separation performance in CO2. The morphology of the IL modification by using scanning electron microscopy (SEM) proved the well dispersion of SAPO-34 subjected to improve polymer/filler interface. The fourier transform infrared spectra (FTIR) were also confirmed that IL was successfully incorporated into MMM and recorded to check the existence bond in the membrane sample. The post-impregnation of the membrane with IL improved the interface contact between the polymer and zeolite. The interface sealing using 0.2M IL enhanced the CO2 permeance, both of the CO2/N2 and CO2/CH4 selectivity of IL-modified MMM, about 319.73 %, 601.69 % and 605.84 % higher than the CO2/N2 and CO2/CH4 selectivity of unmodified MMMs.
