Preparation of PES hollow fiber membranes and their O2/N2 Permeation Properties |
| 초록 |
Polyethersulfone (PES) having a high glass transition temperature of 230℃ was reported to have high O2/N2 selectivity of 6.0. In this study, PES was used as a membrane material and NMP and acetone were employed as a good solvent and non-solvent addictive, respectively. Dope solutions were prepared by changing the content of acetone in 37 wt% PES solutions. Hollow fiber spinning was performed at 0-10cm of air-gap distances for each dope solution. O2/N2 selectivity and permeability were investigated by comparing of hollow fibers coated or not by silicon. O2/N2 selectivity increased and permeabilities of O2 and N2 decreased with increasing air-gap height due to acetone additions. Optimized PES hollow fibers were obtained with 37/6.5/56.5 wt% PES/acetone/NMP dope solution and 10 cm air gap. |
