摘要: Structural, thermal and electrical behavior of polymer-clay nanocomposite electrolytes consisting polymer (polyethylene oxide (PEO)) NaI as salt with different concentrations organically modified Na + montmorillonite (DMMT) filler have been investigated. The formation nanocomposites changes in the structural properties materials were investigated by X-ray diffraction (XRD) analysis. Complex impedance analysis shows existence bulk material-electrode interface composites. relative dielectric constant (er) decreases increase frequency low region whereas independent is observed high region. modulus representation a loss feature imaginary component. relaxation associated this stretched exponential decay. Studies dependence formalism suggest that ionic segmental motion are strongly coupled manifeasting peak (M") spectra no corresponding spectra. ac (alternating current) conductivity obeys Jon- scher power law region, where dispersion indicating presence electrode polarization effect materials.
