Impedance spectroscopy study of poly(ethylene oxide) sodium hexafluortitanate complex

In this work, P(EO)(8)Na2TiF6, P(EO)(24)Na2TiF6 and P(EO)(31)Na2TiF6 comple xes have been investigated analyzing electric properties concerning relaxat ion and diffusion processes. A diffusion-migration model was used to simula te the charge transport mechanism. This model allowed to evaluate the catio n majority contribution to this mechanism. Activation energies of migratory and diffusion processes were estimated on the basis of Arrhenius's equatio n due to the linear dependence of conductivity and diffusion coefficients w ith temperature, typical for semi-crystalline materials.
