摘　　要：采用空气等离子体对聚丙烯微孔膜进行表面改性,用X射线光电子能谱,扫描电镜表征膜表面形态和微观结构的变化。考察了改性膜的水接触角、水通量以及在浸没式膜-生物反应器中的动态抗污染性能力。结果表明,改性后聚丙烯微孔膜的水接触角从100°减小到40°,膜的水通量提高,污染率下降。改性后聚丙烯微孔膜的亲水性和抗污染能力得到较大提高。The modification of surface polypropylene microporous membrane is to improve its antifouling characteristics by plasma treatment.The morphological and microstructure changes of the membrane surface have been confirmed by XPS and SEM.The contact angle,water flux and antifouling property of SMBR have also been studied.The results indicate that the contact angle decreases from 100° to 40°,the fouling ratio of the membrane falls down though the water flux reduces,the hydrophilic and antifouling property of the grafted membrane are improved.
