基于静电纺丝技术制备的超滤膜具有高通量、高截留率的特点,但在过滤过程中容易受到污染,导致通量降低。通常采用表面处理的方法提高静电纺纳米纤维超滤膜的抗污染能力,介绍了几种常见的表面处理方法,包括涂覆法、界面聚合法和溶液处理法,归纳了3种方法的具体步骤及其改性效果。 Ultrafiltration membranes based on electrospinning technology have the characteristics of high throughput and high rejection, but they are easily contaminated during the filtration process, resulting in lower flux. Surface treatment methods are usually used to improve the anti-pollution ability of electrospun nanofiber ultrafiltration membranes. Several common surface treatment methods are introduced, including coating method, interfacial polymerization method and solution treatment method. The specific steps of the three methods are summarized And its modification effect.
