    Progress in Functionalized Polyethersulfone Membranes

    • 摘要: 聚醚砜膜作为综合性能优异的聚合物膜材料,在包括血液净化以及水处理在内的多个领域都得到了广泛应用。然而,聚醚砜膜材料也面临本身的血液相容性较差、渗透率和选择性难调节等问题。因此,聚醚砜膜的功能化改性受到了越来越多关注。本文简要介绍了常用的聚醚砜膜改性方法,总结了近年来对聚醚砜膜进行功能化改性的研究进展,包括用于血液净化的抗凝血、抗污染、抗菌功能改性,可控的环境刺激-响应功能膜,以及用于污水处理的具有吸附功能的聚醚砜膜材料。最后展望了功能化聚醚砜膜未来的研究及发展方向。

       

      Abstract: As a type of polymeric membrane with excellent comprehensive performance, polyether sulfone (PES) membrane is widely applied in many fields, including blood purification and water treatment fields. However, there are still some drawbacks exist during the current application of PES membranes: the main disadvantage is related to its relatively hydrophobic character. Membrane fouling is directly related to the hydrophobicity, which is caused by adsorption of nonpolar solutes, hydrophobic particles or bacteria. Meanwhile, when contacting with blood, proteins will rapidly adsorb onto the surface of the PES membrane and the adsorbed protein layer may lead to further undesirable results, such as platelet adhesion, aggregation and coagulation. As the consequence, the antifouling property and blood compatibility of PES membranes need to be improved. In addition, PES membrane is stable in water. Being an inert membrane, PES membrane acts only as a barrier in the separation process. Thus, the performances of PES membrane would be weakened upon unavoidable membrane fouling, and they cannot be applied in cases where self-regulated permeability and selectivity are required. As a result, smart PES membrane which can self-regulate their permeability and selectivity via the flexible adjustment of pore sizes and surface properties also needs to be developed. With the aim of achieving these purposes, endowing the PES membranes with special functions by various modification methods has aroused more and more attention. In this review, the widely used modification methods for functionalized PES membranes were briefly introduced. Meanwhile, the recent studies of design and fabrication of PES membranes with various functions were summarized, including: (1) the anticoagulation, antifouling and antibacterial membranes for blood purification and biomedical engineering; (2) the stimuli-responsive membranes with switchable permeability and selectivity; (3) the modified membranes with improved adsorption performance for wastewater treatment. Finally, we give the future perspective of the research and development directions of the functionalized PES membranes.
