Micellar Size as a Function of Pressure, Temperature, and Salt Concentration for a Series of Cationic Surfactants
The size, shape and structure of the micellar aggregates formed from ionic surfactants are believed to be influenced by a variety of variables1’2. These include the surfactant composition (hydrocarbon “chain length” and headgroup species) and molarity; the counterion species and concentration; and finally temperature and pressure. Pioneering studies of micelle size as a function of temperature and salt concentration have been made using the powerful technique of quasi-elastic light scattering spectroscopy by Benedek’s group at MIT3–5, Corti and Degiorgio6,7, and others8,9.
