Abstract :
The viscosity and morphology of gemini surfactant in aqueous solution at various temperatures are investigated by rheometer and transmission electron microscopy with a freeze fracture replication technique. The viscosity of 18-3-18 or 16-3-16 reaches its maximum when the solution temperature is near the Krafft temperature of the surfactant. The morphology of a gemini surfactant in aqueous solution is strongly influenced by the temperature: vesicles or sphere-like aggregates are formed in the dilute solution of 18-3-18 under 25 °C environment; when the solution temperature goes up to 50 °C, such aggregates will transit to worm-like micelles with the length of each from 100 nm to 400 nm; meanwhile, the increase of concentration may lead to the formation of network; however, the worm-like micelles or network will transit to vesicles or sphere-like aggregates again when the temperature reaches 80 °C.
