Characterization of Blend Electrolytes Containing Organic and Inorganic Nanoparticles

Abstract

Gels of PVA/PVP polymer nanocomposite electrolytes filled with gradient contents of SiO₂ and MWCNT were fabricated using a solution casting technique. The interaction of the polymer nanocomposite electrolytes was confirmed by FTIR investigation. The Electrical conductivity was calculated with an impedance analyzer within the frequency range 50 Hz–1 MHz at a temperature range 293–343 K has the highest ionic conductivity with 10 wt. % of MWCNTs and 6 wt.% of SiO₂. The real dielectric constant was higher at lower frequencies. Faster-conducting electrolyte ions appeared to require less energy to move, according to the reduction in activation energy. Differential scanning calomatric thermograms showed a single glass transition temperature that confirms the miscibility of PVA and PVP together with the nanoparticles.
