Electrical properties of PVA/PANI/LiI composite membranes.

ABSTRACT: This study centers on polyvinyl alcohol and polyaniline films infused with lithium iodide as polymer electrolyte membranes that conduct ions for various electrochemical applications. Electrolyte membranes made from a 90:10 weight percent blend of polyvinyl alcohol (PVA) and polyaniline (PANI) were synthesized with varying amounts of LiI (from 5 to 25% by weight) via solution casting. The samples were analyzed through X-ray diffraction (XRD), Fourier transform infrared (FT-IR), mechanical properties testing, AC impedance spectroscopy, and linear sweep voltammetry (LSV). X-ray diffraction results show that the amorphous nature of PVA enhances with more additives, and LiI incorporation leads to improved mechanical properties in composite samples. FTIR analysis highlighted interactions between
