Spinodal decomposition in microemulsions

Microemulsions – A Brief Introduction

Nevertheless, the existence and application history of the microemulsions goes back to the very older times, but the oldest available reports in this field have been published by Schulman (Schulman & Hoar, 1943) and Winsor (Winsor, 1954). Their works are the starting point of efforts for the systematic understanding of the microemulsions. Meanwhile, the widespread generalization and application...

Rheological behavior of microemulsions.

We study the stationary and transient behaviors of a microemulsion phase subjected to a shear flow. The system is described by a diffusion-convective equation that generalizes the usual Cahn-Hilliard equation. Nonlinear terms are treated in a self-consistent approximation. Shear, first and second normal stresses are calculated as momenta of the structure factor. Shear thinning is observed in st...

Curvature Elasticity Models of Microemulsions

We review the theory of curvature elasticity of thin" fluid films starting with a phenomenological formalism motivated by microscopic, physical examples. The effects, of finite compressibility 'of the layer, exchange of molecules between the film and the solution, and the intrinsic bending stiffness of the film are taken into account· these degrees of freedom account for all the" important mole...

Uses and applications of microemulsions

Since the discovery of microemulsions, they have attained increasing significance both in basic research and in industry. Due to their unique properties, namely, ultralow interfacial tension, large interfacial area, thermodynamic stability and the ability to solubilize otherwise immiscible liquids, uses and applications of microemulsions have been numerous. The objective of this review is to pr...
