“…Some authors [11][12][13], using dynamic light scattering, studied droplet size and interactions and concluded that the interactions decreased according to their structure. It is well Scheme 1. known that changes in the interactions between droplets are correlated with changes in the value of the percolation temperature.…”

“…These results suggest that the micelle-micelle interactions are notably influenced by the additive species and concentration solubilized into the reverse micelles. Proteins 19,20 and additives 17,21,22 in reverse micelles has been studied by several authors. There are indications that cytochrome c interacts with the AOT surfactant layer.…”

The relationship between the behaviors of c.c.lipase back-extraction and their percolation phenomena by using AOT reverse micellar systems (RVMS) has been studied by the addition of a small amount of additives to organic phase such as thiols and nonionic-surfactants focusing on micelle-micelle interactions. The values of β t defined by the variation of percolation processes and back-extraction behaviors of c.c.lipase have a good linear correlation. The hydrophobicity of additive molecules suppressing the cluster formation of reverse micelles (high values of β t ) improved the back-extraction behavior of c.c.lipase. The back-extraction fraction and its rate of c.c.clipase are increased with decreasing of the value of hydrophilic lipophilic balance (HLB) and increasing of the hydrophobicity per additive molecules added to reverse micellar systems (RVSM) in the same additives concentration.

“…One considers that droplets fluctuate and collide under the effect of electric field, which makes the surfactant molecules transit, so the microemulsion is conductive [15]. The other opinion claims that the conductivity of microemulsion is due to the transition of electrolyte ions in water pools at the oil phase/water phase interface film [16]. The electrical conductivities of microemulsions of 10 mL TritonX-100, 20 mL n-hexanol, 20 mL n-hexane and 4 mL water phase with different HCl concentrations were measured, and the results are shown in Fig.1.…”

A water-in-oil (W/O) microemulsion composed of Triton X-100, n-hexanol, n-hexane and water solution with hydrochloric acid was prepared. K 3 Fe(CN) 6 was added in as a water-soluble electroactive probe, and its electrochemical behavior was investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). It is found that the H + concentration of the water phase has a great effect on the conductivity of the W/O microemulsion, and hence influences the electrochemical behavior of K 3 Fe(CN) 6 . When the pH value of water phase is about 7, the electrical conductivity of the W/O microemulsion is only 1.2×10 −6 S/cm, and K 3 Fe(CN) 6 almost cannot react at the glassy carbon electrode. But when the H + concentration is more than 3 mol/L, the W/O microemulsion has a good electrical conductivity and K 3 Fe(CN) 6 shows good electrochemical performance in it. The results of CV and EIS studies indicate that the electrochemical behavior of Fe(CN) 6 3− /Fe(CN) 6 4− in the W/O microemulsion is different from that in the aqueous solution. This may be due to the unique liquid structure of the W/O microemulsion and the unique mass transfer in the W/O microemulsion.
