CO2 and H2 selectivity properties of PDMS/PSf membrane prepared at different conditions
The effects of different solvent/water coagulation mediums, different coagulation bath temperatures (CBT) and different coagulants on the performance, morphology and thermal stability of polysulfone membranes were investigated. The CO 2 /CH 4 , H 2 /CH 4 and H 2 /N 2 separation performance of the me...

-dimethyl acetamide (DMAc)/water coagulation medium ratio from pure water to 90/10 vol%, resulted in a complete disappearance of the macrovoids throughout the polysulfone (PSf) polymeric matrix.

Using methanol as a coagulant resulted in a less selective membrane compared with membranes from ethanol and water coagulants. The H

permeances were respectively about 3 and 9 times more than those for ethanol and water coagulants. Coated membranes were heated at different temperatures to investigate the suppression of undesirable CO

plasticization. The membranes were stabilized against CO

plasticization by a heat-treatment process. |
