摘　　要：临界胶束浓度是表面活性剂自聚形成胶束的重要参数。双子表面活性剂是具有双亲水基团、双疏水链的表面活性剂,比常规表面活性剂具有更低的临界胶束浓度和更高的表面活性。了解影响双子表面活性剂临界胶束浓度的内在、外在因素,有助于理解分子间的相互作用,分析碳链和联接基团等分子结构对其性能的影响,探究双子表面活性剂的自组织行为,从而更好地发挥双子表面活性剂的高表面/界面活性,开发新型高效表面活性剂。文中介绍了双子表面活性剂临界胶束浓度常用的测定方法,总结了双子表面活性剂疏水基团、联接基团、亲水基团、温度、无机盐等对双子表面活性剂临界胶束浓度的影响,并对影响结果进行了分析。Critical micelle concentration is an important parameter in surfactants self-assembly behavior.Gemini surfactant is a kind of surfactant with double carbon chain and double hydrophilic group.It has a lower CMC than that of traditional surfactant.This means that it has much higher surface activity.To understand the inner and external factors affecting CMC can help us to understand the interaction between molecules,analyze the influence of molecular structure including carbon chain and spacer group on property,explore Gemini surfactants self-assembly behavior and make better use of good surface/interfacial properties of Gemini surfactants and explore new products.This paper introduced the usual methods of measuring CMC.It also summarized the influences of many parameters such as hydrophobic group,spacer group,hydrophilic group,temperature and salt on CMC and analyzed the results.
