Membrane separation processes develop as one important separation technique in chemical industries. In general, membrane can be classified as membrane designed for water/waste water treatment and membrane for gas separation. The industrial application of membrane for gas separation is not as wide as for water/waste water treatment. This phenomenon occurs mainly because the gas permeability-selectivity trade-off experienced by gas separation membranes, especially polymeric membranes. To overcome this trade-off problem, the combination of polymeric material and inorganic fillers inside mixed matrix membranes (MMMs) arises as a rapid growing field of research in gas separation membrane topic. Until recently, the problem of void and defects formation in MMMs is still hamper the real application of MMMs. One particular aspect that still needs a deep understanding is the compatibility issue between polymer and particle. Hence, this study focuses on the synthesis and characterisation of MMMs from two different polymer matrix, such as polysulfone and cellulose acetate, and two particles, i.e. ZIF-8 and TiO2 to analyse the chemical and morphological of the produced membranes. From SEM and EDX analysis, ZIF-8 particles dispersed more continuously than TiO2. At FTIR wave number of 800 cm-1 – 1,100 cm-1, it has been found that both particles formed chemical bonding with C-O-C ring of polysulfone that could potentially improve the mechanical and plasticization resistance of the membranes. XRD analysis also indicated an increase in degree of crystallinity of MMMs after the incorporation of particles. These results indicate the potentiality of MMMs from this study to be applied as gas separation membranes for CO2/N2 gas mixtures.
