The effect of a minimum amount of octyl-β-D-glucoside on micellar, nematic, and hexagonal phases of the CTAB/glycerol/water system

The incorporation of a minimum amount of octyl-beta-D-glucoside (1 wt%) in the ternary CTAB/glycerol/water and CTAB/glyceraldehyde/water systems helps the formation of a nematic liquid crystal at 30 degreesC. Moreover, the presence of octyl-beta-D-glucoside enlarges the micellar and the hexagonal phases. The nematic phase appears between the micellar and the hexagonal liquid crystal phases. It changes to an isotropic phase at 34 degreesC. The rheological study of the different phases is shown. The presence of octyl-beta-D-glucoside affects the structure of the micelles. The incorporation of octyl-beta-D-glucoside leads to micelles at highest amounts of CTAB and glycerol, which change their structures under shearing.
