Polymer nanocomposite electrolytes comprising poly(ethylene oxide) (PEO) and lithium triflate (LiCF<sub>3</sub>SO<sub>3</sub>) with varying concentration of montmorillonite (MMT) nano-platelets as filler were synthesized by direct melt compounded hot-press technique at PEO melting temperature. The complex dielectric function, electric modulus, alternating current electrical conductivity and complex impedance spectra in the frequency range 20 Hz-1 MHz at ambient temperature have been investigated. The <i>dc</i> conductivity shows an increase of about one order magnitude with optimum value at 2 wt% MMT. The correlation of conductivity relaxation time and the predominance of MMT intercalated structures with <i>dc</i> ionic conductivity in these solid electrolytes have been recognized, which confirm the potential use of dielectric relaxation spectroscopy for the online processing of melt compounded PNCEs materials. |
