Vesicle-lamellar transition events in DDAB-water solution Academic Article uri icon

abstract

  • Double-tailed ionic surfactants form lamellar liquid crystalline phases with water. Here, we have used cryo-transmission electron microscopy (cryo-TEM) technique to study the transition to a lamellar phase at dilute aqueous solutions of the cationic surfactant didodecyldimethylammonium (DDA) with different counterions: acetate (DDAAc), hydroxide (DDAOH), bromide (DDABr), sulphate (DDAS), as well as the anionic surfactant sodium bis (2-ethylhexyl) sulfosuccinate (AOT). Vesicles are observed in all the double-tailed …
