Structural transformations in TTAB aggregated binary systems

Abstract
Abstract Structural transformations in TTAB aggregated systems have been investigated using positron lifetime spectroscopy. Positron lifetime measurements have been carried in TTAB/water and TTAB/pentanol binary solutions as a function of surfactant concentration. In TTAB/water, molecular aggregation sets in at a surfactant concentration of ~ 3.5 mM(CMC). Several changes in micellar structure as a function of surfactant concentration are indicated. In TTAB/pentanol binary solutions, evidence for molecular aggregation is seen. With increasing surfactant concentration other structural transformations are indicated.
