对制备稳定的微乳液体系过程的分析与探讨

Analysis and investigation of the processing of the preparation of stable micro-latex system

在利用微乳液技术制备复合导电粒子的过程中,微乳液的稳定性是关键。所以在制备稳定的微乳液体系过程中应注意几点问题:首先要明确微乳液是热力学的稳定体系,是一个自发过程,不需要额外补充能量;其次是正确地选择乳化剂和助表面活性剂;再者要掌握正确地制备方法。判断是否是稳定的微乳液体系就要看该乳液在静置的情况下不分层、透明或半透明的液体。本文主要讨论W/O型的微乳液体系。

The stability of micro- latex is a key problem in preparation complex conducting particles with micro- latex technology, so that a litter problem must noted in making stable micro - latex： first of all, it must be bear in mind that micro - latex is a steady system in thermodynamic, it is a spontaneous process, and that non - energy is supplied in the system; secondly, emulsifying agent and secondary surface active agent are exactly selected; thirdly, preparation technique must be had. A steady micro- latex system is not layered, transparent or semitransparent.The text is the discussion of micro - latex system for W/O.
