The Preparation and Structural Study of PVA: NH4I Nano Composite Polymer Electrolyte System

The composite polymer electrolyte system based on Polyvinyl alcohol (PVA) doped with Ammonium Iodide [NH4I] with different weight percent ratios have been prepared by solution cast technique which is further sonicated by UV Sonicator to disperse the nanoparticles in the solution. Structural properties were studied by X-ray diffraction (XRD) technique which confirms the polycrystalline nature of thin film with a preferred orientation along (002) plane. The complex formation of salt with the polymer was confirmed by Fourier transform infrared (FTIR) Spectroscopy. Hence from FTIR spectroscopy and XRD the interaction between PVA and Ammonium iodide [NH4I] and their complex formation have been confirmed. Hence, Material can be used for different applications like Electrochemical Devices, Sensors, Fuel Cell and Dye sensitised Solar Cell.
