| Research Abstract |
A microemulsion (ME) is low-viscosity, isotropic, thermodynamically-stable, spontaneously-formed solution phase composed of water, organic solvent and surfactants. The dynamic morphology of a ME is determined by the characteristics of the surfactant in the emulsion system. When the hydrophilicity and lipophilicity of a surfactant in a system are well-balanced, the ME reveals a bicontinuous structure, a so-called middle phase microemulsion (MPME, Winsor III). In an MPME, the water phase and the oil phase coexist alternately on a microscopic scale as a bicontinuous structure. In a previous letter, we reported the simultaneous electrochemical response of the Fe(CN)_6 ion and ferrocene, which are distributed in the saline and toluene phases, respectively, of the MPME. The unique characteristics of an MPME are essentially based on the very delicate balance between the hydrophilicity and lipophilicity (HLB) of the surfactant system, which is moderated by the concentrations of cosurfactant and salt. It would be expected that the local structure of an MPME on a surface changes according to the characteristics of the surface. Therefore, the electrochemistry of redox molecules in an MPME was investigated using various electrodes, such as indium tin oxide (ITO), gold disc (Au), glassy carbon disc (GC), highly oriented pyrolytic graphite (HOPG) and alkane thiol-modified Au(SAM) electrodes. In addition, it was fond that the gelation in middle phase microemulsion, which bicontinuously composed of saline and toluene microphases, was lead to form continuous porous gels and nano composite gels between oil gel and aqueous gel.
