Effect of spinning conditions on the structure and the gas permeation properties of high flux polyethersulfone– polyimide blend hollow fibers
In this work, the effects of major spinning parameters, such as: polymer concentration, air gap distance, bore fluid composition, and take-up velocity on the structure and the permeation properties of polyethersulfone... and selectivity coefficients (a CO2/N2: 40). These results compete directly with the performance of commercial gas separation membranes. PES/PI blends can be successfully prepared in the form of asymmetric hollow fibers by using the dry/wet spinning process. The structure and the permeatio ...
