Abstract: This research investigated the effect of solvent evaporation time and the effect of acetone as a co-solvent on the fabrication process of polysulfone (PSF) membrane using the dry/wet phase inversion technique. The morphology of the sample membrane was verified by using a scanning electron microscope (SEM). The results showed that the Immediate immersion of the polymer film in the coagulation bath did not show any porosity. The increasing the evaporation time of the solvent increased the mean diameter of the pores and the porosity of the membrane. The PSF membrane produced by using mixed dimethylformamide (DMF) and acetone as a solvent provided a smaller pore size radius and a lower porosity than that produced by using only DMF.
