- 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.
