摘要
低聚表面活性剂是指通过连接基将两个以上的传统表面活性剂连接在一起而形成的一类新型表面活性剂。相对于对应的传统表面活性剂,这类表面活性剂具有临界胶束浓度(cmc)低、表面活性高等优点。本文介绍了本研究团队近年针对低聚表面活性剂所开展的研究,包括分子结构不对称的双子表面活性剂、同时具有阳离子和阴离子头基的甜菜碱型双子表面活性剂、三聚和四聚阳离子表面活性剂以及通过原子转移自由基聚合制备的低聚表面活性剂等。
Oligomeric surfactants are a novel family of amphiphilic molecules possessing two or more than two surfactant ＂monomers＂ linked by spacers.Compared with corresponding surfactants,oligomeric surfactants show much lower cmc and much higher surface activities.Presented in this paper are our recent work on oligomeric surfactants,including dissymmetric gemini surfactant with different hydrophobe length,or different nature of hydrophobic tail,or different hydrophilic heads,and alkylbetaine zwitterionic gemini surfactants,trimeric and tetrameric surfactants.Atom transfer radical polymerization was found an useful tool to prepare oligomeric surfactants.
