Defect-free asymmetric Polysulfone (PSF)-Cloisite 15A® nanocomposite membrane was fabricated with the intention to investigate the gas permeation behavior of the resulting material combination. Various weights of Cloisite 15A® organoclay were added into PSF matrices by solution intercalation method assisted by sonication dispersion. The gas permeation properties of the PSF-Cloisite 15A® nanocomposite membranes were evaluated by pure gases: nitrogen, methane, and carbon dioxide. The distribution of Cloisite 15A® particles in PSF matrices was analyzed by SEM. The gas flux of the PSF-Cloisite 15A® nanocomposite membranes declined as the Cloisite 15A® weight loading increased. The CO2/CH4 and CO2/N2 pure gas selectivity of PSF nanocomposite with 0.5 wt. % of Cloisite 15A® loading exceeded that of neat PSF membrane. The decrease in flux followed by the increase in pure gas selectivity was related to the way in which the clay layers were dispersed in the PSF matrices. Considerable improvement in CO2 selectivity was attainable even by incorporating low amount of such layered structure nanoparticle which can be attractive in producing robust materials for CO2-removal membranes from CO2-containing gas streams such as post-combustion and natural gas streams
