采用硅橡胶涂层聚醚酰亚胺膜对乙酸/水混合物进行渗透汽化分离。特别是，聚醚酰亚胺膜的孔径和硅橡胶涂层的条件对复合膜的性能的影响进行了研究。结果发现，复合膜可以成为水选择性或乙酸选择性，这取决于支撑膜的孔径和硅橡胶涂层的条件。因此，复合膜的整体性能可以由顶部涂覆层或底部支撑层控制
Separation of acetic acid/water mixtures by pervaporation was attempted by silicone rubber-coated polyetherimide membranes. In particular, the effect of the pore size of the polyetherimide membrane and the condition of silicone rubber coating on the performance of the composite membrane was investigated. It was found that the composite membrane could become either water selective or acetic acid selective, depending on the pore size of the support membrane and the condition of the silicone rubber coating. Thus, the overall performance of the composite membrane can be governed, either by the top coated layer or by the bottom support layer
