摘要
本文从分析蠕虫胶束形成的分子几何条件和自由能驱动因素入手,总结了传统阴离子表面活性剂蠕虫胶束的形成和性质,指出制约其构筑和产生优良黏弹性的原因。在此基础上,介绍了Gemini表面活性剂构筑蠕虫胶束的分子结构优势,以及由此构筑阴离子蠕虫胶束的研究进展,尤其是长刚性联接链Gemini表面活性剂形成的蠕虫胶束。最后特别指出,基于新颖分子结构优势,Gemini表面活性剂可望成为蠕虫胶束构筑的主要分子对象。
The molecular geometry and the driving factor of Gibbs free energy are acted as the preconditions for wormlike micelle construction. Bearing this in mind, the formation and properties of the wormlike micelles by conventional anionic surfactants are summarized. The reasons restricting the wormlike micelle formation and high viscoelasticity in conventional anionic surfactant systems are illustrated. The molecular structure advantage of Gemini surfactant in forming wormlike micelles is introduced. Recent advances in anionic wormlike micelle construction, especially for those formed by anionic Gemini surfactants with long and rigid spacer are described in detail. Finally, as a conclusion, it is specially pointed out that based on the superiority of novel molecular structures, Gemini surfactants could become main candidates in constructing wormlike micelles.
