The effect of adding tri(oxyethylene) dodecyl ether (C12EO3) on the phase and rheological behavior of sucrose hexadecanoate and CTAB aqueous solutions in the presence of added salt (NaBr) was investigated. Viscoelastic solutions are formed in CTAB and C16SE systems upon addition of lipophilic nonionic surfactant C12EO3. The zero-shear viscosity shows a maximum at a certain mixing fraction of C12EO3, except in the case of the aqueous CTAB/C12EO3 system in the absence of salt. The rheological properties are strongly affected by the addition of salt to the CTAB systems but they remain unaltered in the case of C16SE systems. In ionic systems, the mixing fraction of C12EO3 for the maximum viscosity depends on salt concentration.
研究了添加三（氧乙烯）十二烷基醚（C12EO3）对十六烷酸蔗糖酯和十六烷基三甲基溴化铵（CTAB）水溶液在添加盐（NaBr）情况下的相行为和流变行为的影响。在CTAB和十六烷酸蔗糖酯（C16SE）体系中加入亲脂性非离子表面活性剂C12EO3后形成了粘弹性溶液。除了在无盐的CTAB/C12EO3水溶液体系中，零剪切粘度在C12EO3的特定混合分数下出现最大值。盐的添加对CTAB体系的流变性质有强烈影响，但在C16SE体系中流变性质保持不变。在离子体系中，使粘度达到最大值的C12EO3混合分数取决于盐浓度。
