Abstract

Thermoplastic polyurethane(PU)-based blend membranes were prepared by the solvent evaporation process. The gas sorption, diffusion, and permeation properties of PU-based blend membranes have been studied. The morphology of PU-based blend membranes was investigated by SEM. The result showed that phase separation occurred with increasing blend ratio. $CO_2$ permeation behaviors of blend membranes were affect by blend composition. Thermoplastic polyurethane(PU)-based membranes showed high $CO_2$ permeation and $CO_2$/$N_2$ selectivity of the blend membrane was improved with increasing the blend ratio.
