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.
