Conductance and Viscosity of Microemulsion with Anionic Surfactant

应用电导法和黏度法研究了AOT/异辛烷/水微乳液,AOT/异辛烷在质量比4∶5和35℃时,测定不同含水量的电导率和黏度.实验结果表明,含水量0.13～0.20时,电导率随含水量的增大基本保持不变,含水量0.20～0.30时,电导率随含水量的增加不断升高,含水量0.30～0.40时,电导率随含水量的增大不断下降;含水量0.13～0.25时,黏度随含水量的增大不断增大,含水量0.25～0.35时,黏度随含水量的增大基本保持不变,含水量0.35～0.40时,黏度随含水量的增大不断增大.

AOT/isooctance/water microemulsion is studied by the conductance and viscosity methods. The conductivity and viscosity of microemulsion with different water contents are measured at mass ratio 4 ： 5 of AOT/isooctance and at 35 ℃. Experiments indicate that along with the increase of water content, the conductivity retains constant between 0. 13 and 0.20;it continuously increases between 0.20 and 0.30, but continuously decreases between 0.30 and 0.40 ;the viscosity continuously increases between 0.13 and 0.25 ;it retains constant between 0.25 and 0.35,but continuously increases between 0.35 and 0.40.
