超临界流体在制膜过程中的应用

Applications of supercritical fluids in membrane preparation

介绍了超临界流体诱导相分离过程制备有机膜的工艺流程、原理及特点,并与传统的沉浸凝胶相转化制膜方法进行了比较。同时介绍了超临界流体过程在有机膜的制备和改性方面的研究现状及其研究前景,并对其进一步的研究提出了一些建议。

The process,principle and characteristics of preparing organic membrane by supercritical fluids inducing phase separation are described and compared with the traditional wet phase inversion process.The technical process of membrane preparation by super- critical fluids,the current status of study and the foreground of re- search are introduced.In addition,membrane modification with su- percritical fluids is presented.Some proposes on the further research are put forward.
