Abstract

Kinetics of Lamellar to Gyroid Transition in a Nonionic Surfactant System has been investigated by means of a small angle x-ray scattering (SAXS) technique. For large ΔT (ΔT=T-T_LG, T: temperature, T_LG: lamellar to gyroid transition temperature) in the lamellar phase, the SAXS profiles can be described by a structure factor for undulation fluctuation lamellae. Approaching the temperature to the T_LG, an excess diffuse scattering grows at lower Q (Q: magnitude of scattering vector) side of the first lamellar peak. This diffuse scattering arises from the modulation fluctuation of lamellar layer. At the T_LG, the PFL transformed to the gyroid phase through a transient ordered structure having a rhombohedral symmetry.
