以非离子型表面活性剂所组成的微乳液为研究对象,通过测定流变性、粘度、电导和NMR等实验,研究其微观结构.实验表明:在不同水油比范围内有不同结构,在层状结构区也有异常流变性,对此现象有了进一步理解.

Optically transparent oil-water dispersions (microemulsions) formed spontaneously upon mixing oil (hexadecane, kerosine,dodecane), hexanol, AEO9 (C14H29O(CH2CH2O)9H), and water in specific proportions. Microemulsion viscosities were measured for several oil-water ratios. The striking optical and viscosity changes observed at specific water/oil ratio = 0.58 are consistent with a lamellae structure. The microstructure is discussed to explain the experimental viscosity, optical property, NMR, and neg. thixotropy results.

Key words: NON IONIC SURFACTANTS, C12 COMPOUNDS, RHEOLOGICAL PROPERTY, KEROSENE, HEXANOL, EMULSIFYING LIQUID, MICROEMULSION
