摘要
聚偏氟乙烯(PVDF)超滤膜由于膜污染影响其使用寿命,目前关于其抗污染改性研究已成为研究焦点之一。分别从亲水改性材料、功能改性材料、界面改性材料3类抗污染改性材料角度对PVDF超滤膜抗污染改性研究成果进行了综述,并介绍了几种潜力抗污染改性材料。最后,对3类抗污染改性材料存在的局限性进行了分析,并对抗污染改性材料的未来发展作出展望,如膜抗污染改性领域中普遍存在的Trade-off效应的解决途径。
PVDF ultrafiltration membranes have become one of the focal points of research on their anti-pollution modification due to the influence of membrane contamination on their service life.The research results on the anti-pollution modification of PVDF ultrafiltration membranes were reviewed from the perspectives of three types of anti-pollution modification materials:hydrophilic modified materials,functional modified materials and interfacial modified materials,and several potential anti-pollution modification materials were introduced.Finally,the limitations of the three types of anti-pollution modifiers were analyzed,and the future development of anti-pollution modifiers such as the Trade-off effect,which was prevalent in the field of membrane anti-pollution modifications,was also prospected.
