particle size onthe gas separation properties of Polysulfone MMM [20]. Hussain
and König [26] prepared MMM based on Poly(dimethylsiloxane)
with different compositions of ZSM-5 to study CO2 separation from
gas mixtures. The gas separation performance of MMM was evaluated
using the modified Maxwell model. Pechar et al. [27] reported
the correlation of gas permselectivity with the addition of Zeolite L
for thin film membranes made from polyimide while certain gas
permeabilities in the membrane increase with the addition of Zeolite
L. Overall, these MMMs did not offer substantial selectivity
improvement.
