Abstract:

The study of the relaxation properties near the percolation threshold in ternary water-in-oil microemulsion stabilized by ionic surfactant are presented as an example of the dynamics in self-assembled complex fluids. The data treatment for dynamic behavior of the microemulsions was carried out in the time domain in terms of dipole correlation functions. The correlation functions exhibit complex non-exponential relaxation behavior and must be de-convoluted into normal modes and represented as the sum of non-exponential terms; exp[-(t/$\tau$)$\beta$]. The temp. dependence of the stretched parameters shows the existence of spatial, temporal, and energetic disorder assocd. with anomalous diffusion of charge carriers in the percolation clusters.
