Effect of tyoe of solvents on asymmetric polyethersulfone PES) membrane for CO2/H4 separation

This study investigates the influences of solvent on the structure and performances of polyethersulfone asymmetric flat sheet membrane for gas separation. The asymmetric flat sheet membrane were prepared by dry/wet phase inversion process consisting polyethersulfone (PES) as polymer, distillate wate...

The asymmetric flat sheet membrane were prepared by dry/wet phase inversion process consisting polyethersulfone (PES) as polymer, distillate water as a non-solvent and different solvent type was also added either dimethylformamide (DMF), dimethylacetamide (DMAc) or N-methyl-2-pyrrolidone (NMP).
