Abstract
By optimizing the CNT loading and pH of the membrane, the CO2 permeance was increased from 0.18 ± 0.02 m3 (STP)/m2 bar h to 0.44 ± 0.02 m3 (STP)/m2 bar h at a constant CO2/N2 selectivity of 60 ± 1. The membrane swelling degree was also increased from 154 ± 20 to 254 ± 30. The thickness of the selective layer was reduced from â¼0.85 µm to 0.45 µm which resulted in further increase in permeance to 0.48 m3 (STP)/m2 bar h. The developed membrane showed a stable operation over a period of 1 month.
