十二烷基硫酸钠（SDS）/Brij 30/H2O体系的相行为由相图示出。该体系可形成胶束、反胶束、各向异性层状和六方液晶区。在振荡频率扫描实验中，粘弹溶液的流变行为在低剪切频率下符合麦克斯韦模型，在高剪切频率下偏离麦克斯韦模型，这是蠕虫状胶束缠结形成瞬态网络的典型特性。此外，通过动态光散射和冷冻断裂图像，这是一致的流变行为的结果进行了评估。
The phase behavior of the sodium dodecyl sulfate (SDS)/Brij 30/H2O system is shown by a phase diagram. The system can form micelle, reverse micelle, anisotropic lamellar, and hexagonal liquid crystal regions. The rheological behavior of the viscoselastic solution follows the Maxwell model at lower shear frequencies and deviates from it at higher shear frequencies in the oscillatory frequency sweeping experiment, which is the typical property of wormlike micelles entangled to form a transient network. In addition, the results are evaluated by dynamic light scattering and freeze-fracture images, which are consistent with the rheological behavior.
