Structural, Thermal and Electrical Studies of Al2O3 Nanoparticle Soaked Electrolyte Gel Films for Novel Proton Conducting (H+ ion) Eco-friendly Device Applications

An attempt has been made to prepare and characterize ammonium acetate (NH4CH3COO) salt and Aluminium Oxide (Al2O3)-soaked polyvinyl alcohol (PVA) based [PVA-NH4CH3COO:×wt%Al2O3] system nanocomposite polymer gel electrolyte (NCPGE) films using a solution cast technique. The SEM and XRD studies revealed improvement in amorphous nature. The degree of crystallinity and average crystallite size of electrolytes with respect to Al2O3 were projected to ascertain improvement in amorphous nature. FTIR studies confirmed the complexation between PVA, NH4CH3COO and Al2O3. The DSC studies show better thermal response upon addition of Al2O3 nanofiller. TGA studies reveal the mass of nanocomposite polymer gel electrolyte decreases continuously with increase in the Al2O3 nanofiller contents. Closer assessment of conductivity behavior shows two maximas: one around 0.5wt% and the other around 1wt% filler concentration which is a typical feature for nanocomposite gel polymer electrolytes. The temperature dependence of electrical conductivity shows a combination of Arrhenius and Vogel–Tamman–Fulcher (VTF) behavior. The ionic conductivity is found to increase with addition of filler concentration and optimum ionic conductivity of 3.88×10−4 Scm−1 with wide electrochemical stability of ±4.78V is achieved at 1wt% Al2O3 nano filler and confirms the availability of H+ ion (proton) in the system suitable for the development of environment friendly rechargeable batteries application.
