STUDY OF DYNAMICAL AND STRUCTURAL-PROPERTIES OF MICROEMULSIONS BY CHEMICAL PHYSICS METHODS

In an attempt to elucidate structural properties, high resolution NMR, NMR proton relaxation time, viscosity, and electron microscopy experiments have been run on microemulsions (water, toluene, sodium dodecyl sulfate, n-butanol). Results are in good agreement with water/oil, oil/water, and perhaps lamellar structures. They show a continuous evolution between all these structures; inversion zones have been pointed out. Over all the stability domain, the surfactant is responsible for the membrane-like structure, and fast molecular dynamics seems to be a fundamental parameter of the stability. © 1979.
