本文以聚二甲基硅氧烷（PDMS）为膜材料，乙烯基三乙氧基硅烷（VTES）为交联剂，在聚偏氟乙烯（PVDF）中空纤维支撑膜表面通过交联反应制备出PDMS/PVDF中空纤维渗透汽化复合膜。采用扫描电子显微镜和全反射傅里叶红外光谱仪表征复合膜的形貌和结构变化。研究了膜对正丁醇-水、异丙醇-水及丙酮-水三种模拟含盐有机废水的分离效果，并考察了温度对膜性能的影响。结果表明：PDMS/PVDF中空纤维膜对这三种模拟含盐有机废水有较好的分离效果，操作温度为40oC时，膜的渗透通量分别为275.95 g/(m2?h)、322.16 g/(m2?h)、489.76 g/(m2?h)，分离因子为37.82、12.60、33.12。
