Mixtures of water, oil, and surfactant often form microemulsions where tiny drops of oil (or water) are dispersed in a matrix of water (or oil). A microemulsion is a partially-ordered fluid in which the surfactant molecules exist in an oriented layer at the boundary between the continuous phase and
The thermodynamics of microemulsions is treated by decomposing the Helmholtz free energy into a sum of a free energy F0 of a dispersion in a continuous medium containing fixed, noninteracting globules and a free energy DeltaF due to the entropy of dispersion of globules in the continuous medium and
