摘　　要：阴离子/两性表面活性剂在协同作用下可自组装形成蠕虫状胶束。阴离子表面活性剂十二烷基硫酸钠(SDS)和疏水作用较强的两性表面活性剂十六烷3-磺丙基二甲甜菜碱(SB3-16)可在无盐条件下形成蠕虫状胶束。通过流变学表征,研究了蠕虫状胶束的黏弹性,分别探索了表面活性剂比例、总浓度以及温度对于蠕虫状胶束黏弹性的影响。所得研究结果可为表面活性剂复配体系构建蠕虫状胶束提供参考。Wormlike micelles can be formed by the synergetic effect in the anionic/zwitterionic surfactant system.The wormlike micelles can be constructed by dodecyl sulfate sodium(SDS)and 3-(N,N-dimethylpalmitylammonio)propanesulfonate(SB3-16)without the aid of salts.With the help of rheological characterizations,the surfactant ratio,total concentration and temperature effects have been explored on the viscoelastic properties of wormlike micelles.The obtained results will provide a reference for the construction of wormlike micelles in the mixed surfactant system.
