Synthesis and Spectral Characterization on Pva/Pvp: Go Based Blend Polymer Electrolytes

Abstract

Graphene oxide (GO) nanoparticles were dispersed in PVA/PVP blend polymers for preparation of nanocomposite polymer films by solution cast technique. SEM analysis revealed that graphene oxide is completely dispersed in blend polymer of PVA/PVP, resulting in the smooth surface background corresponds to amorphous nature of the host polymer. Raman spectra of PVA/PVP: GO; (0.30/0.3) is recorded in the wavenumber range 600-3250 cm -1 at room temperature. DSC is used to measure the glass transition temperature (Tg) as a function of wt% ratios of PVA/PVP:GO polymer electrolyte film and revealed that the glass transition temperature decreased monotonically, due to a lubricating effect with the increase of GO wt% (up to 0.3 wt %) to the blend polymers. AC conductivity studies were performed onto the prepared nanocomposite polymer films. The conductivity is found to be 4.13x10 -4 Scm-1 for the films prepared at room temperature.

The electrical and mechanical properties of Cadmium chloride reinforced PVA:PVP blend films

“…It can be observed that the loss factor decreases as the frequency increases for all the polymer blend films. This may be attributed to the enhancement of the charge carriers that takes place across the electric charge area, decreasing the value of the loss factor at high frequencies until the electron's energy is equal to the Fermi level [11].…”
