Abstract
In this study, metal oxides of Strontium oxide (SrO) and Lanthanum oxide (La2O3) were incorporated into a polymer blend of polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), and polyethylene glycol (PEG). Specifically, the blends PVA-PVP-PEG, PVA-PVP-PEG-SrO, PVA-PVP-PEG-La2O3, and PVA-PVP-PEG-SrO-La2O3 were prepared using casting techniques enhanced by ultrasonic casting methods. The resulting polymer membranes exhibited both semi-crystalline and amorphous characteristics, with the addition of SrO and La2O3 leading to prominent crystalline peaks. The electrical properties of these polymer blends were analyzed using impedance spectroscopy and an I-V source meter, which allowed for the determination of their resistance ranges. Notably, the PVA-PVP-PEG-SrO-La2O3 membrane exhibited a significant elongation of 102.6%, as indicated by Young’s modulus measurements, underscoring its potential use as an active layer for flexible electronics applications.
