Abstract

A transition from micelles to vesicles is reported when salts are added to a catanionic micellar soln. composed of Na dodecylcarboxylate (SL) and dodecyltrimethylammonium bromide (DTAB), with an excess of SL. The counterion binding and increase in aggregate size was monitored by mass spectrometry, rheol. and dynamic light scattering measurements, whereas the vesicles were characterized by ...
