Abstract:
 Poly(ether sulfone) (PES) and copoly(phthalazinone biphenyl ether sulfone) (PPBES) were used as membrane materials to prepare PES/PPBES blend ultrafiltration membranes. The effect of blend ratio of PES to PPBES on the compatibility and the viscosity of casting solution and the properties of ultrafiltration membranes were investigated by differential scanning calorimetry, fourier transform infrared spectrometer, rotational viscometer, contact angle measuring instrument, scanning electron microscopy and universal material testing machine. The experimental results show that when the content of PPBES was less than 20% in the blend, PPBES and PES had good compatibility; in these experiments, the hollow fiber ultrafiltration membrane showed a high rejection of bovine serum albumin (BSA), and with the increase in PPBES content of the blend, the pure water flux increased significantly. The membrane’s hydrophilicity was greatly improved. When the PPBES content was 30 wt%, the pure water flux of PES/PPBES blend membrane could reach 60.5 L/m2.h, which was about 2.5 times the flux of PES membrane.
