This research work focuses on the fabrication of mixed matrix membranes (MMMs) for the enhancement of CO 2 removal from CH 4 . Zeolitic imidazolate framework (ZIF-8) with a framework of 0.34 nm pore size which favours CO 2 adsorption is used as filler in this work. Different loadings of ZIF-8 filler were incorporated into polysulfone (PSf) polymer matrix. From the EDX mapping, the morphology of the ZIF-8/PSf MMMs has shown compatibility between the polymer and filler phases. The MMMs demonstrated an increment of 8°C in glass transition temperature, Tg compared to the pure PSf. Based on the permeation results, MMM loaded with 1 wt% of ZIF-8 showed the highest performance with CO 2 and CH 4 permeability of 33.12 Barrer and 0.85 Barrer respectively, and CO 2 /CH 4 ideal selectivity of 38.8. The development of this new type of MMM has great potential to be utilized in CO2/CH4 separation process.
