Production of super selective polysulfone hollow fiber membranes for gas separation

Preparation and characterization of porous PVDF hollow fiber membranes for CO2 absorption: Effect of different non-solvent additives in the polymer dope

“…The spinning solutions were degassed for 24 h at room temperature before spinning. The hollow fiber spinning process by the dry-jet wet phase-inversion was explained elsewhere (Ismail et al, 1999). Table 1 lists the detailed spinning parameters.…”

Fabrication and characterization of hydroxylated and carboxylated multiwalled carbon nanotube/polyethersulfone (PES) nanocomposite hollow fiber membranes

“…Hollow fibers have been found to be a particularly efficient geometry for many membrane applications [5][6][7][8] due to the high surface to volume ratios (packing density) and favorable mass transfer properties. Hollow fiber membranes are fabricated using a process known as spinning.…”

Polysulfone membranes for CO2/CH4 separation: State of the art

“…Many researches were done to find the optimum PSf membrane formulation. A formulation that has been used widely to make ultra thin defect free PSf membranes [21,22,23,24,25,26] was given by Pesek and Koros [27]. Performances of those membranes are given in Table 1.…”

“…Increasing shear rate enhances molecular orientation in selective layer and offers a chance to increasing membrane selectivity [21,24]. According to research by Sharpe et al there is an optimum shear rate to produce defect free ultra thin PSf membrane.…”
