Based on the {S+, I-} pathway, the concentration of surfactant and surface charge density of silanolate groups control the phase transition from lamellar, to hexagonal through cubic form. The high surface charge density of silanolate groups was observed for the lamellar phase. With decrease of molar concentration of surfactant on the gel, the yield of...
