双子表面活性剂的综述

Overview of Gemini Surfactant

双子表面活性剂是一类新型的表面活性剂,它是由联结基团通过化学键将两个或多个单体表面活性剂连接在一起形成的表面活性剂。由于其优异的性质越来越受到国内外学者的重视。与传统表面活性剂相比较,双子表面活性剂在降低表面张力、聚集生成胶团、Krafft点和临界胶束浓度(CMC)等性能上都明显更加的优异。文章就它的性能和应用等方面进行介绍。

Gemini surfactants are a new type of surfactants, in which the two or more monomers are linked with the chemical bond by spacer groups. Because of the excellent properties of Gemini surfactants, more and more attention is paid by scholars at home and abroad. Compared with a conventional surface active agent, the surface tension of the Gemini surfactant at a reduced, aggregation generated micelles, Krafft point, critical micelle concentration （CMC） and other properties were more excellent significantly. In this paper the properties and applications of Gemini surfactants are introduced.
