摘要
聚丙烯中空纤维膜因具有不对称膜的特性以及单位膜面积大、分离效率高等优点被广泛应用于水处理等分离领域。但由于聚丙烯的疏水性导致其应用受限,而聚丙烯中空纤维膜的亲水改性是拓展其应用的重要手段,因此研究其亲水改性具有重要的意义。简要介绍了聚丙烯中空纤维膜及应用,着重论述了改善其亲水性的各种方法和最新进展,并对聚丙烯中空纤维膜亲水改性的发展方向进行了展望。
Polypropylene hollow fiber membrane due to the characteristics of asymmetric membrane and the advantages of the large specific surface area and high separation efficiency is widely used in water treatment and other areas of the separation. But the hydrophobic of polypropylene leads to its application is limited, and the hydrophilic modification of polypropylene hollow fiber membrane is an important means of expanding its application. The study of the hydrophilic modification of polypropylene hollow fiber membrane is of great significance. The polypropylene hollow fiber membrane and its application is simply introduced. The hydrophilic modification of various methods and the latest progress of polypropylene hollow fiber membrane is described in detail, and hydrophilie modification of polypropylene hollow fiber membrane for the future development direction is discussed.
