摘要
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 die 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.
