Abstract

Micelles are species of colloidal dimensions, which form in solutions as a result of the reversible aggregation of relatively small molecules of amphiphilic character, the monomers1. Molecular weights monomers do not usually exceed several hundreds, these of micelles are ranging from a few thousands to millions. Most amphiphilic solutes contain a hydrophobic flexible chain moiety and a polar group. The hydrocarbon chains form a liquid—like core, the polar groups are exposed to water at the surface. The small micelles are roughly spherical and can be looked upon as a monolayer curved on itself. For its characteristics micelles serve as models for many interfacial, colloidal and membrane—like systems. With increasing monomer concentration of an aqueous solution micelles start to form at so called critical micelle concentration (CMC) as a result of the three kinds of interactions: the hydrophobic interaction, the interaction between head groups and the interaction between head groups and the hydrocarbone core. The number of monomers per micelle i is called the aggregation number. The moderately sized micelles ( ranging from 50 to 1 40) do not increase in size much over considerable intervals of concentrations and exhibit a low degree of polydispersity. The total micelle concentration [M ] can.be related to the detergent (monomer) concentration ED] as EM]=flcmc).
