Abstract

Dodecyltrimethylammonium triflate (DTATf) micelles possess lower degree of counterion dissocn. (α), lower hydration, and higher packing of monomers than other micelles of similar structure. Addn. of sodium triflate ([NaTf] > 0.05 M) to DTATf solns. promotes phase sepn. This phenomenon is commonly obsd. in oppositely charged surfactant mixts., but it is rare for ionic surfactants and relatively ...
