Abstract
The most promising approaches to making polysiloxane-based membranes more selective are considered. These approaches can be subdivided into three groups: (1) development of new membrane materials by copolymerization, (2) modification of the polysiloxane chain (in the backbone and pendant chains), and (3) development of mixed matrix membranes. All the three approaches are subjected to a critical analysis, and conclusions are made on the prospects for the development of high-selectivity materials and high-performance membranes based on them. The data are presented from the viewpoint of applied aspects of polysiloxane-based membranes.

用于气体和液体分离的高选择性聚硅氧烷膜(综述)
摘要
考虑了使聚硅氧烷基膜更具选择性的最有前途的方法。这些方法可以细分为三组:(1)通过共聚开发新的膜材料,(2)聚硅氧烷链(在主链和侧链中)的改性,以及(3)混合基质膜的开发。对这三种方法都进行了批判性分析,并对基于它们的高选择性材料和高性能膜的发展前景做出了结论。这些数据是从聚硅氧烷基膜的应用方面的角度呈现的。
