Membrane separation of polysaccharides has broad prospects. To improve the efficiency of separation, an ultrafiltration membrane with both hydrophilic surface and temperature response (expansion and contraction) were prepared. By comparing filtration performance of the polyethersulfone (PES) membrane, the temperature response membrane (PCG) which is modified by the blend microgel, and the sulfonated polyethersulfone-co-gel (SPG) membrane which is obtained by introducing sulfonic acid groups into PCG membrane at different temperatures, the SPG membrane performed the best anti-pollution capacity. Depending on the results at 30 ℃, the water flux of SPG increased by 45.98% and the polysaccharide flux increased by 10.80%, while the water flux of the SPG membrane increased by 96.68% and the polysaccharide flux increased by 26.10% at 40 ℃. After washing at a regulated temperature, the membrane flux recovered to 80.41% of the initial flux. Meanwhile, after reducing the temperature of the polysaccharide solution to 20 ℃ for half an hour, and then returning to 50 ℃, the membrane flux also recovered significantly, about 106.38% of the initial flux.
