Abstract

Blend polymer electrolytes were prepared with different wt% compositions of [PVA/PVP-MgCl2·6H2O] : % using solution cast technique. Structural, morphological, vibrational, thermal, and ionic conductivity and electrochemical properties were studied on the prepared polymer films. XRD revealed the crystalline nature of the polymer electrolyte films. The morphology and the degree of roughness of the prepared films were analyzed by SEM. FTIR and Raman studies confirmed the chemical complex nature of the ligands, interlinking bond formation between the blend polymers and the dopant salt. The glass transition temperature () of polymer electrolytes was confirmed by DSC studies. Ionic conductivity measurements were carried out on the prepared films in the frequency ranging between 5000 Hz and 50000 KHz and found to be maximum (2.42 × 10−4 S/cm) for the prepared film with wt% composition 35PVA/35PVP : 30MgCl2·6H2O at room temperature. The electrochemical studies were also performed on the prepared films. The galvanostatic charge/discharge performance was carried out from 2.9 to 4.4 V for the configuration Mg+/(PVA/PVP + MgCl2·6H2O)/(I2 + C + electrolyte).
