As environmental consciousness is urge throughout the world to reduce the emission of carbon dioxide (CO2) gas, researcher has been working on a way to separate the gas and store them where they belong. CO2 presence in atmosphere will coat the earth and trap amount of heat and further cause climate change. In this study, a mixed matrix membrane (MMM) will be produced in order to separate CO2 gas from emitted to the atmosphere. The MMM is produced by the combination of polyvinylidene fluoride (PVDF) and Zeolite via dry/wet phase inversion technique. The invention of this MMM is expected to improve the separation performance of pure PVDF membrane. PVDF is introduced with an inorganic filler, Zeolite with ratio of N-Methyl-2-pyrrolidone (NMP) (solvent): PVDF: Zeolite 80:10:10, 80:15:5, and 80:5:15 in order to achieve the desired selectivity and permeability which will be tested on CO2/N2 gas separation. From the performance view, the MMM with composition 80:15:5 are the most suitable to separate the two gases compared to pure PVDF membrane as the permeance of CO2 and N2 were recorded at 17631.41 GPU and 2041.30 GPU respectively at 0.5 atm. The result also unbeatable when the pressure was increased up to 1 atm, the permeance of CO2 and N2 are 13370.49 GPU and 4558.12 GPU respectively. These high performance samples are prove by the SEM image of the surface morphology itself. The pore diameter ranges of 0.58µm-1µm are the result of pore disruption by the zeolite nanoparticles.
