Some aspects of droplets dispersed in a five-component w/o microemulsion

Comparative Study on the Structure of Reverse Micelles. 2. FT-IR, 1H NMR, and Electrical Conductance of H2O/AOT/NaDEHP/n-Heptane Systems

“…The charge carriers move through the clusters under electrical field, which results in dramatic increase of conductivity. , The percolation threshold corresponds to the formation of the first infinite clusters of droplets. It has also been reported that the morphology of droplets in AOT microemulsions changes from an almost spherical one to a prolate ellipsoid when the amount of water increases …”

An Experimental Study on the Relationship between the Physical Properties of CTAB/Hexanol/Water Reverse Micelles and ZrO2–Y2O3Nanoparticles Prepared

“…The microstructure, structure transition, phase behavior, and water uptake of reverse micelles have been extensively studied (2, 4, 10 -16). The size and shape of reverse micelles would change with the w 0 value (w 0 , molar ratio of water to surfactant used), electrolyte concentration of aqueous phase, type of ions in the aqueous solution, and type of cosurfactant used (2,3,17). Droplets with spherical, ellipsoidal, rod-like, cylindrical, or planar shapes would appear with changing w 0 or electrolyte concentration in the aqueous phase.…”

“…Such thermodynamically stable systems have been called water in oil (w/o) microemulsions or reverse micelles. Due to their importance in various technological applications, such as the enhancement of oil recovery, preparation of pharmaceuticals, cosmetics, and monodispersed nanoparticles, more and more studies from both theoretical and experimental aspects have been carried out to provide a better understanding of the physical and chemical properties of reverse micelles (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). The microstructure, structure transition, phase behavior, and water uptake of reverse micelles have been extensively studied (2, 4, 10 -16).…”

Approximate Analytical Expressions for the Electrical Potential in a Cavity Containing Salt-Free Medium

“…Both the case of constant surface potential and that of constant surface charge density are considered. The result obtained in this study has potential usage, for example, in the prediction and/or interpretation of several specific behaviors, such as clustering and electrical percolation, of lipid-stabilized water-in-oil microemulsions, [19][20][21][22][23] where the electrical interactions between dispersed liquid entities is believed to play an important role. [24][25] The results derived in this study are also applicable to the modeling of the electroosmotic flow in a microchannel containing salt-free solutions.…”
