Dynamics of Intermicellar Exchanges
Micelles are dynamic assemblies and a number of processes involving micelles occur spontaneously in micellar solutions /1–3/.The two most important processes are the intermicellar exchanges through which material (surfactant and any kind of solubilized compound: alcohol, oil, fluorescent probe, reactant, etc...) is exchanged between micelles and the process of micelle formation-breakdown.The time scale for these processes stretches from second to nanosecond.This is why their study was performed using fast kinetics methods, chemical relaxation /4/ and time-resolved fluorescence probing /5/ being the most extensively used.In the following the term micelle refers to simple or mixed micelles as well as micelles containing solubilized molecules and droplets of oil or water in oil in water or water in oil microemulsions.
