초록정보

Dielectric behavior of various reverse micelles with water was investigated. In AOT-based system, the percolation phenomenon was observed as temperature increases under appropriated water existing. Below the percolation temperature, microemulsion seems to be insulator, but above that point systems become a conductor. The conductivity of system increases by two orders of magnitude. The process of percolation is not revealed exactly. However both two theory of percolation mechanism, "ion hopping" and "transient fusion-mass transfer-fission", contribute to conductivity enhancement partially. In addition to, we tried to do dynamic percolation scaling by using bulk effective scaling function of heterogeneous mixture of insulator and conductor. From temperature dependency of AOT dielectric & conductivity, we can have conclusion that water as defects that move through the liquid lead diffusive relaxation. In contrast to in AOT - base system, in lecithin-base system the charge transport mechanism is done through the channel of interconnected reverse micelles. Water in lecithin-gel system plays a role of stimulating to branch off. We proved the gel structure is formed so charge transfer through this cluster spanning.
