Abstract:Polyethersulfone(PES), polysulfone(PSF) and sulfonated polysulfone(SPSF) binary and ternary alloy ultrafiltration membranes were prepared and studied in this paper. The relationship between the membrane performance and the composition or miscibility of the alloy system and the characterization of the pore size distribution of membrane were discussed. The pore formation mechanism of alloy ultrafiltration membrane was also preliminary studied in this paper. The results showed that, polymer blend could improve the ultrafiltration membrane performance and pore size distribution. Polymer blend was one of the effective methods to prepare high performance ultrafiltration membrane.
Keywords:ultrafiltration membrane  polymer blend  polyethersulfone(PES)  polysulfone(PSF)  sulfonated polysulfone(SPSF)
