摘　　要：制备了聚醚砜(PES)中空纤维膜,并研究了膜的结构和性能。通过研究成分和工艺条件对聚醚砜中空纤维膜形态和性能的影响,掌握了膜的结构和性能的关系。采用浸渍沉淀相转化法,通过改变聚醚砜在溶液中质量比、空气浴时间、凝固浴组成等参数来调节膜的性能。运用纯水通量和扫描电子显微镜对膜的形态和性能进行表征。结果表明,聚合物质量比、凝固浴组成等工艺参数对膜的形态影响较大,通过工艺条件的组合,可制得具有良好性能和理想结构的中空纤维膜。The sheet polyethersulfone（PES） hollow fiber membranes were prepared.The morphology and performance of the membranes can be controlled.By studying the influence of the compositions and conditions on the morphology and performance of PES hollow fiber membrane,the relationship of morphology and performance of the membrane is acquired.Immerse phase inversion was used for membranes preparation.The performance of the membrane was controlled by changing the mass ratio of PES,air setting time,and so on.It was found that the membrane morphologies were changed by the temperature of coagulation bath obviously.Pure water flux and scanning electron microscopy（SEM） were used to characterize the morphology and performance of the membranes.From the study,the parameters for membrane preparation with good performance and ideal structure were summarized.
