摘要
报道了正戊醇对CTAB/KBr胶束体系流变性的影响.结果表明:在0.01mol·dm^(-3)CTAB(十六烷基三甲基溴化铵)溶液中,正戊醇促使CTAB/KBr胶束体系的粘度增大至一最大值,然后降低.在0.08mol·dm^(-3)CTAB/0.8mol·dm^(-3)KBr的溶液中,正戊醇能促使该胶束体系呈现粘弹性.根据动态荧光法测定的胶束聚集数对以上结果进行了解释.
The effect of n - pentanol on the rheological properties of CTAB/KBr micellar systems has been investigated. The addition of n ?pentanol induces the viscosity of CTAB/KBr micellar system to go through a marked maximum in 0.01 mol·dm-3CTAB/KBr solution. In 0.08 mol ·dm-3CTAB/0.08 mol·dm-3 solution, a small amount of n - pentanol can make CTAB/KBr system have viscoelasticity, when the n - pentanol concentration increases continuously, the viscoelasticity of this micellar system decreases. Finally, we discuss these results in terms of the micellar aggregation number determined from time resolved fluorescence spectrophotometry.
