聚醚砜膜亲水改性研究进展

Research Progress on Hydrophilic Modification of Polyethersulfone Membrane

聚醚砜膜具有优异的性能,能够应用于生物医药、精细化工、环境保护和食品工业等领域,但是其具有疏水性,容易造成膜污染、膜寿命降低等问题。文章介绍聚醚砜膜亲水改性常用的3种方法如,表面涂覆改性、表面接枝改性和共混改性法,综述近3年PES膜亲水改性最新的研究进展,对聚醚砜膜未来的发展趋势进行展望。研究表明:为得到成本低廉,适用于大规模工业化生产的PES亲水材料,对改性方法仍需深入探索。

Polyethersulfone membrane has excellent performance, which can be used in biomedical, fine chemical,environmental protection and food industry. However, Polyethersulfone membrane has hydrophobicity, which is easy to cause membrane pollution and reduce membrane life. Three common methods of hydrophilic modification of polyethersulfone membrane, such as surface coating modification, surface grafting modification and blending modification are introduced. The latest research progress of hydrophilic modification of PES membrane in recent three years is reviewed, and the future development trend of polyethersulfone membrane is prospected. It is pointed out that in order to obtain PES hydrophilic materials with low cost and suitable for large-scale industrial production, the modification methods need to be further explored.
