Phase behavior of poly(oxyethylene) cholesteryl ether/novel alkanolamide/water systems

Lyotropic liquid crystalline phases formed in ternary mixtures of 1-cetyl-3-methylimidazolium bromide/p-xylene/water: A SAXS, POM, and rheology study

“…4 (plotting scattering vectors versus Miller indexes). All of the parameters calculated from the SAXS results were also obtained according to the equations and theory [26][27][28][29][30][31][32] shown in the supporting information, and the values are listed in Table 1. It can be seen from Table 1 that, for the hexagonal phase, when the ratio of the weight fraction of p-xylene:water is fixed, the values of the lattice parameter (a 0 ), the radius of the cylinder unit (r H ), and the thickness of the water channel (d W ) all decrease as the C 16 mim-Br content increases.…”

Wormlike micelles in poly(oxyethylene) surfactant solution: Growth control through hydrophilic-group size variation

“…In dilute aqueous solutions of poly(oxyethylene) cholesteryl ether surfactants spherical micelles are formed at room temperatures [32] and increase in temperature promotes unidimensional micellar growth [33]. These surfactants, in binary systems and with cosurfactants, show interesting phase behavior, in which a rectangular phase or a defected lamellar phase in addition to conventional liquid crystals appear [32,34].…”

Effect of Cyclohexane on the Phase Behavior of L64/1-Butyl-3-Methylimidazolium Tetrafluoroborate System

“…[15] The SAXS characterization of the L a phase is based on the long-range order in the liquid crystalline state, and the relevant structural parameters can be calculated from the SAXS results according to the equations and theory. [15,24] For L a phase the lattice periodicity (d) is given directly by the position:…”
