Abstract
Zirconium oxide (ZrO2) nanomaterials were synthesized by hydrothermal method using ZrOCl2,8H2O and KOH as precursors. The as-synthesized ZrO2 was characterized by powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FT-IR), Field Emission Gun Scanning electron microscopy (FEG-SEM), transmission electron microscopy (TEM) and Brunaur-Emmett-Teller (BET) surface analysis. The synthesized ZrO2 nanomaterial is used to prepare composite 2,5 polybenzimidazole (ABPBI) polymer membrane. The nanocomposite membrane was further gone through various characterisation processes as mechanical stability, X-ray diffraction (XRD), contact angle measurement, Electrochemical impedance spectroscopy (EIS) and Field Emission Gun Scanning electron microscopy (FEG-SEM). The influence of ZrO2 nanoparticle for preparing composite polymer membrane to use in Vanadium redox flow battery as a separator was studied. The investigation shows significant improvement in mechanical stability and robustness, enhancement in ionic conductivity of the nanocomposite membrane and excellent battery performance. Figure 1
