Effect of Al2O3 Nanoparticle on the characteristic Parameters of PVDF-co-HFP Based Mg2+ Conducting Polymer Electrolyte Membranes

Abstract

Solution casting technique was cast-off to create a novel kind of magnesium ion conductive nanocomposite polymer electrolyte membrane. The films include dissimilar weight percentages of Al2O3 nanofillers embedded in the congregation polymer PVDF-co-HFP, containing magnesium triflate Mg(CF3SO3)2. The distinctive crystalline phases of the polymer and its segment dynamics are considerably changed by changes in the component content of these SPEs. The structural morphology of these films were characterized by the techniques such as FTIR, DSC, SEM, and XRD. Fourier transform infrared spectroscopy (FTIR) was used to affirm the chemical composition of the polymer electrolyte membrane, Differential scanning calorimetry (DSC) was used to verify a decline in melting temperature, Scanning electron microscopy (SEM) was used to affirm the exterior morphology of the film, and Xray diffraction (XRD) was used to ensure the drop in crystallinity. It was observed that 8wt% of Al2O3 exhibits the best among them. The addition of nano filler was found to trigger the band of C–O–C stretching to move to a lesser wave number and the strength of the peaks to drop, signalling that the films' crystalline nature had changed to an amorphous one.
