两性离子基团改性超滤膜研究进展

Research Progress of Modified Ultrafiltration Membrane with Zwitterionic Group

膜污染的问题正限制着膜技术的进一步扩大应用,而两性离子聚合物具有亲水基团,能高度水化从而阻抗非特异性蛋白的吸附,因此,通过接枝改性技术将两性离子引入到膜材料中,制备耐污染性膜具有重要的研究意义.该文综述了两性离子聚合物在超滤膜领域的应用进展,对膜改性方法进行了分类,并展望了其应用前景.

The problem of membrane fouling limits the further application of membrane technology, and zwitterionic polymer with hydrophilic group, the height of hydration can prevent nonspecific protein adsorption. So by grafting the zwitterionic to the membrane materials has important significance. The article mainly reviews the application of zwitterion polymer in the field of uhrafihration membrane, and classifies the modification methods, predicts their future prospect.
