Rheological behaviours of the hexagonal and lamellar phases of glucopone (APG) surfactant

Phase behaviour and thermodynamic properties of lamellar liquid crystal developed for viscoelastic surfactant based fracturing fluid

“…This corresponds to high density connection points of the micelles in the lamellar liquid crystal as strong interactions are developed within and among the monodomains. No crossover point was observed between both the viscoelastic functions in the frequency range studied, which confirms the presence of lamellar liquid crystals (Cordobes et al, 2005;Siddig et al, 2006;Ya et al, 2006).…”

Phase equilibria of mixtures of surfactants and viscoelastic properties of the liquid crystal phases

“…The H 1 phase for C 12 E 4 contents higher than 15% in the mixture coexist with lamellar phase. Similar values of the relaxation times were obtained for hexagonal phase of glucopones surfactants [31]. The elastic properties ware also associated to the area per surfactant molecule.…”

An HII liquid crystal-based delivery system for cyclosporin A: Physical characterization

“…There have been only a few rheological studies for monoolein liquid crystalline systems [32][33][34][35]. The rheological behavior of the H II systems is even less known, both for GMO and for other surfactant systems [17,36,37].…”
