The phase behavior and ionic conductivity of a new class of hydrated-salt/surfactant lyotropic liquid-crystalline (LLC) mesophase is investigated. The LLC samples were prepared by adding each ingredients such as salt, surfactant, and water in the required amounts and the resulting mixture was then homogenized by constant shaking in a shaking water bath at 60-110 8C for 24 h. A large region in the phase diagram belongs to a hexagonal LLC mesophase. At a moderate water/salt mole ratio, the salt/surfactant mole ratio can be varied between 2 and 8 to form stable LLC mesophases. The ionic conductivity shows a nearly Arrhenius-type relation with temperature. However, deviations increase as the temperature is lowered. The switching time, robustness, and the stability of the system suggest that the LLC gel electrolyte is a promising candidate for the electrochromic devices and optical displays.
