CTAB微乳液的电导和黏度研究

Conductance and Viscosity Study of CTAB Microemulsion

应用电导法和黏度法研究了CTAB/正丁醇/苯/水微乳液,在CTAB-正丁醇-苯3种物质的质量比1∶1∶2和35℃条件下,测定不同含水质量分数的电导率,以及不同含水量的黏度.实验结果表明:含水质量分数为4%～20%时,电导率随含水量的增大不断升高;含水质量分数20%～40%时,电导率随含水量的增加基本保持不变;含水质量分数40%～53%时,电导率随含水量的增大不断升高;含水质量分数4%～53%时,CTAB黏度随含水量的增大不断增大,后半段增大速度比前半段稍大.

In this article CTAB/1-butanol/benzene/water microemulsion is studied by conductance method and viscosity method. The conductivity and viscosity of microemulsion with different water contents are measured at mass ratio 1：1：2 of CTAB/1-butanol/benzene and 35 %. Experiments indicate that, along with the increase of water content, the conductivity continuously increases between 4 % and 20 %, retains constant between 20 % and 40 %, continuously increases between 40 % and 53 %;the viscosity continuously increases between 4 % and 53 %,and increases slightly faster after 30 %.
