湿法相转化制膜过程对膜结构的影响

Effect on Structure of Formed Membrane through Wet-Phase Inversion Technique

论述了湿法相转化制膜过程的各个环节对膜结构的影响。控制制膜条件，形成不同结构的膜。湿法相转化制膜过程包括：铸膜液的制备、在平板玻璃上形成均匀的液膜、预蒸发、浸入凝固浴中凝胶化和膜的热处理及预压处理。

In this paper was discussed the effect on the structure of the membrane formed via wet-phase inversion technique. Different membrane structures could be obtained by changing the conditions of membrane formation. The process of phase inversion generally includes: the preparation of casting solution, a symmetrical thin film of solution formed on a plane glass, pre-evaporation, gelation in coagulation bath, heat treatment and pre-press treatment
