Abstract
Mixed matrix composite membrane has attracted many researchers to develop due to the excellent ability in gas separation. Amine functionalized graphene oxide were used as nanofillers by incorporated amine functional group with graphene oxide. The PEBAX/AGO membrane were fabricated on the top of supporting layer of PSF. In this study, the gas separation performance were investigated by varying the AGO loadings (0.0, 0.25, 0.5and 0.75 (w/w%)) for CO2 gas separation. The synthesis GO and AGO were characterized using FTIR to study the structure before being embedded into PEBAX based membrane. Then, the fabricated membrane were characterized using SEM and FTIR. The selectivity and permeability of PEBAX/AGO-0.5 showed the optimum condition with CO2 permeability 67.1 Barrer followed by PEBAX/AGO- 0.25 with 64.3 Barrer. The result indicated that the permeability increase when AGO loading increased. Additionally, it is found that the additions of nanofillers lead to a significant enhancement in gas permeability especially in amine functionalized GO.
