The Phase Behavior and Structure of SDS/BA/H2O System
Abstract:
Micelle, microemulsion, lamellar liquid crystal and hexa nal liquid crystal can be formed in SDS/BA/H2O system, and the exchanging between them can be explained by the R ratio. The value of distribution coefficient of BA in O/W microemulsion, K=168, shows that most of BA molecules should be solubilized in the SDS micelle phase. With increasing the weight ratio of BA/SDS, d0 values have almost no change and the penetration of solvent, α, slightly increases in the lamellar liquid crystal, and the radius r in hexa nal liquid crystal is almost unchanged and the penetrations of solvent, α, increase in hexa nal liquid crystal.
