以非离子型表面活性剂AEO~9、正十六烷、正己醇和水所组成的微乳液为对象, 研究盐和pH值对其粘度和流变性的影响, 得出它们在pH值为7时最小, 以及二价盐影响最大的结论, 正好与离子型微乳液结果相反, 为此进行了讨论。并从热效应和电导对其微观结构作了初步探索。

关键词: 盐, 非离子表面活性剂, 流变性质, PH

The microemulsion is composed of AEO~9, hexadecane, hexanol and water. The effects of different salts and varying pH values on the rheological properties of the microemulsions were studied on experiment and the mechanism of their rheological properties was discussed. These phenomena can be rationalized with order and unorder arrangements of lamella structures which further conformed be electrical conductivity and thermal effect.

Key words: SALT, NON IONIC SURFACTANTS, RHEOLOGICAL PROPERTY, PH
