The Effect of Doping Cr3+ Ions on Thermal, Structural and Morphological, Properties of PVP Polymer Electrolytes

Abstract

In this work, the method of solution casting were used for the PVP polymer films doped with Cr³⁺ ions at various concentrations (1 to 5 mol%). The TGA, XRD and SEM Characterizations was explained for the structural, thermic and morphology properties of pure and PVP polymer films doped with Cr³⁺. The thermal stability improvement and three different stages of weight losses of the investigated samples were shows dTG data. The X-ray diffraction explains for the increasing amorphousness of the PVP polymer film due to doping. The morphological studies of PVP polymer films doped with Cr³⁺ is nearly bumpy compared to pure film, suggesting the amorphous description.
