Effect of Ethanol Concentrations in Internal Coagulant on the Morphology and Separation Performance of Polyethersulfone (PES) Hollow Fiber UFMembranes Prepared by PES/Ethanol/NMP Solution
Polyethersulfone (PES) hollow fiber UF membranes were fabricated usingethanol (non-solvent) as additive and N-methyl-2-pyrrolidone (NMP) as asolvent.Asymmetric hollow fiber UF membranes were spun by wet phaseinversion method from 18 wt.% solids of 18:10:72 (weight ratio) PES/Nonsolvent/NMP solutions.Effect of ethanol concentrations in internal coag
