摘　　要：制备以聚酯（PET）为支撑层，白炭黑填充的聚二甲基硅氧烷（PDMSl07）为皮层的硅橡胶复合膜，并以乙醇水物系为料液，对比分析白炭黑增强硅橡胶复合膜的渗透蒸发分离性能，分离因子比空白膜有所提高，在乙醇浓度为3％～5％时，分离因子可达16．09，渗透通量为75．39g／m^2·h；测定填充白炭黑硅橡胶复合膜的拉伸强度，结果表明：拉伸强度可达1．828MPa，相当于空白膜（0．368MPa）的5倍。The composite polydimethylsiloxane（PDMS） membranes filled with nano-silica were prepared for the separation of ethanol from water. The pervaporation properties of nano-silica filled silicone rubber membranes was studied by contrast with no filled. It showed that the separation factor was higher than the PDMS composite membrane. During the 3 % to 4 % of the eoncentration of the alcohol the separation and the permeation rate were 16.09 and 75.39 g/m^2 · h respectively. The influence of filling silica on the mechanical properties of the membrane were also studied,the tensile-strength was 1. 828 MPa which was 5 times than the PDMS composite membrane（0. 368 MPa）.
