Aggregation in dodecyltrimethylammonium bromide- didodecyldimethyammonium bromide aqueous mixtures

the characteristics of the aggregation of the aqueous mixed system dodecyltrimethylammonium bromide - didodecyldimethylammonium bromide were studied by several techniques. the mixed systems show a coexistence of small spherical micelles, and a polydisperse mixture of vesicles and aggregates of micelles. the charge and size of aggregates were studied as a function of the mixture composition.
