Nanocomposite polymer electrolytes are of great interest because of their superior properties such as ionic conductivity and mechanical stability over pure polymers. Composite polymer electrolytes are basically formed by dispersing inorganic oxides like TiO2, Al2O3, etc., into a polymer-salt electrolyte solid matrix. In the work, the most common and effective polymeric electrolyte, polyethylene oxide (PEO), incorporated with an organic/inorganic hybrid material, polyhedral oligomeric silsesquioxane (POSS), was fabricated and characterized by means of various techniques such as differential scanning calorimeter (DSC), wide-angle X-ray diffraction (WAXD) and polarized optical microscope (POM). Also, the ion conductivity of the electrolytes was measured using impedance spectroscopy. The POSS suppressed the crystallization of PEO, leading to enhanced ion conductivity. |
