Fabrication of Mixed Matrix Membrane Polysulfone - Zeolite Carbon Composites (ZCC) For Gas Separation

Mixed matrix membrane polysulfone (PSF) - zeolite carbon composite (ZCC) was successfully fabricated in this study. The composition of ZCC as a filler in this membrane was 1%. Mixed matrix membrane PSF-ZCC 1 wt% was compared by neat polysulfone membrane. The prepared membranes were characterized using XRD to determine the membrane structure and FTIR to determine the functional groups in the membrane. The results of gas permeation for membrane permeability of O-2 were 4.011 and 7.193 GPU for neat PSF and PSF-ZCC 1 wt% membrane, respectively. In addition, the permeability value of N-2 was 5.603 and 7.862 GPU for neat PSF and PSF-ZCC 1 wt% membrane, respectively. Selectivities of O-2/N-2 for neat PSF and PSF-ZCC 1 wt% membrane were 0.715 and 0.914, respectively. The increasing permeability along with the addition of ZCC filler indicated that the membrane in this study is potentially applied for O-2 and N-2 separation.
