- Polysulfone/Polyvinylidene fluoride blend (PSf/PVDF) membranes with composition PSf/PVDF/NMP/NH4Cl (wt.%) of 8/6/84/2 supported on gauze fabric were successfully synthesized by a phase inversion method and immersion precipitation technique. Variations of stirring time and cast thickness were used to obtain an asymmetric structure with the least number of macrovoids. Increased stirring time of the casting solution and decreased cast thickness had an effect on the formation of a two layer, asymmetric structure resulted in higher porosity and lower thickness of the porous layer. Not only did it have an effect on the mechanical strength and permeability, the variations of stirring time and cast thickness had an influence on the thermal stability up to 470 ºC, the degradation temperature of the PSf
