Synthesis and Characterization of Thin Film Nanocomposites of PEO/PMMA Blend Using SnO2 Filler

A new approach involving the prologue of tin oxide (SnO2) nanofiller into nanocomposite solid polymer electrolyte system [NSPE] of polyethylene oxide (PEO)/polymethyl methacrylate (PMMA)–cadmium bromide (CdBr2) has been adopted, intending to improve the electrochemical performance of thin film. Thin film specimens of nanocomposite solid polymer electrolytes [NSPE] were synthesized using solution casting technique and typified by diverse portrayal techniques such as X-ray diffractogram (XRD), Fourier transforms infrared spectroscopic analysis (FTIR) and UV–visible spectrophotometry. The XRD studies show the structural changes occurring within the chosen nanocomposite solid polymer electrolyte system. The coordinative interactions taking place within the polymer electrolyte system were revealed by FTIR studies and optical analysis was carried out by UV–visible spectroscopy. Furthermore, all these studies enabled the identification of the interaction of nanofiller SnO2 within these blended polymer electrolytes exhibiting an improved amorphicity, and hence, the present system shows an advanced performance in the case of ion-conducting polymer electrolytes.
