摘要
聚砜具有热稳定性较好、化学性和生物相容性良好、力学强度高的特点,被广泛用于水处理、血液透析、化学生产等领域中。但是,聚砜类材料的疏水性使细菌、有机物易附着在膜表面或微孔中,造成严重的膜污染。为提高膜材料的渗透通量和抗污染性能,需对聚砜膜改性。而两亲性高分子链段中含有亲水链段及疏水链段,可以使膜兼具抗污染性及稳定性。因此,简述了两亲性共聚物对聚砜改性分离膜的研究进展,详细介绍了通过缩合聚合、传统自由基聚合、活性自由基聚合3种聚合方法合成两亲性共聚物,并系统地阐述了相应改性膜的最新研究进展,为两亲性改性膜的商品化生产提供参考。
Due to its good thermal stability/biocompatibility/mechanical properties and stable chemical properties,polysulfone(PSf)is broadly used in water treatment,hemodialysis,chemical production and other fields.However,due to the strong hydrophobicity of the PSf membrane,bacteria,organic pollutents,etc.are easily adhered on the membrane surface or in the micropores during the separation process,resulting in serious membrane pollution problems.In order to improve the permeation flux and anti-fouling performance of the membrane material,the PSf membrane needs to be modified.The hydrophilic segment and the hydrophobic segment are contained in the amphiphilic polymer,which can simultaneously ensure the anti-fouling and stability of the modified membrane.In the article,the research progress of amphiphilic copolymers on PSf modified separation membranes was described briefly.The synthesis of amphiphilic copolymers through three polymerization methods:condensation polymerization,traditional free radical polymerization and living free radical polymerization was elaborated systematically.The latest research results of the corresponding modified membranes were elaborated in order to provide a reference for the commercial production of amphiphilic modified membranes.
