摘要
介绍了自具微孔聚合物(PIMs)及其改性膜材料在渗透汽化膜分离领域中的应用研究进展,评述了在优先脱有机物、优先脱水以及有机混合物分离3个领域中所应用的PIMs膜的分子结构设计、改性方法以及分离效果。PIMs是一种依靠自身分子扭曲而具有大量微孔的新型聚合物,具有憎水性以及均一的孔结构,对于不同体系中的目标分离物均有较好的分离特性,有望成为通用的渗透汽化膜材料。认为开发更多种类的新型PIMs材料及其更多的分离应用,并且有必要关注如何实现PIMs合成的工业放大和提高PIMs膜应用的稳定性等问题。
The application progresses of polymers of intrinsic microporosity(PIMs)and its modified membrane materials in pervaporation membrane separation have been introduced.It was mainly reviewed that the molecular structure design,modification method,and separation performances of PIMs membranes in pervaporation separation of organic compounds from water,water from organic compounds and organic mixtures.PIMs are a new type of polymer with a large number of micropores relying on its own molecular distortion,and it have good separation performances for various targets from different mixtures due to the hydrophobicity and uniform microporous structures.Thus,PIMs are expected to be a kind of versatile membrane materials for pervaporation.It considered that,more types of PIMs with novel structures should be developed,and the industrial scale-up of PIMs synthesis and the improvement of application stability should be concerned.
