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。
In this paper, the molecular geometry of the formation of micelles and the driving force of free energy were analyzed. The formation and properties of the traditional anionic surfactant micelles were summarized. The reasons that constrain their construction and produce excellent viscoelasticity were pointed out. Based on this, the advantages of Gemini surfactant in constructing the molecular structure of worm micelles and the development of anionic worm micelles are introduced, especially the worm micelles formed by long-chain Gemini surfactants. Finally, it was pointed out that based on the novel molecular structure, Gemini surfactant is expected to become the main molecular target of worm micelles.
