Preparation and Characterization of PES/SPSF Blend Ultrafiltration Membrane
Polyethersulfone(PES)/Sulfonated polysulfone(SPSF) blend ultrafiltration membranes at different SPSF contents were prepared using a phase inversion technique. The morphological structures of PES/SPSF blend ultrafiltration membranes with different sulfonation degree were characterized using SEM. The results shown that the PES/SPSF blend ultrafiltration membranes had good retention to PEG1000 (99.8%) and high water permeate flux (27.2Lm-2h-1) at 0.1MPa.
