摘要: 将聚乙烯吡咯烷酮(PVP)修饰在介孔二氧化硅(MS)表面，制成MS-PVP纳米粒子，然后将其加入到聚醚砜中，利用相转化制备出PES/MS-PVP复合膜。利用场发射扫描电镜观察了复合膜的表面和断面形貌，并对复合膜的分离性能进行了测试。将复合膜表面进行荷电改性后，用于天然水体中腐殖酸(Humic Acid, HA)的分离，结果表明，荷电改性复合膜对HA的截留率达96%，可用于饮用水的深度处理。
Abstract: Polyvinylpyrrolidone (PVP) was modified on the surface of mesoporous silica (MS) to prepare MS-PVP nanoparticles, and then added to polyethersulfone. PES/MS-PVP composite membranes were fabricated by phase inversion. The surface and cross-sectional morphology of the composite films were observed by field emission scanning electron microscopy (SEM), and the separation performance of the composite films was investigated. Then the membrane surfaces were charge modified to enhance the separation performance for the (Humic Acid, HA); the results showed that the separation of HA was 96%, which could be used for the treatment of drinking water.
