Sažetak
The preparation of (PEO)8ZnCl2 polymer electrolytes and nanocomposites was performed by using PEO g-irradiated by a selected dose of 309 kGy and TiO2 nanograins. We have studied the influence of the added nanosize TiO2 grains on the polymer electrolytes and the effect of g-radiation from a Co-60 source. For this purpose we have utilized synchrotron technique small-angle X-ray scattering (SAXS) simultaneously recorded with differential scanning calorimetry (DSC). These measurements were performed at SAXS beamline of the synchrotron ELETTRA. Impedance spectroscopy (IS) was also performed and compared with SAXS/DSC results. The conductivity of the polymer electrolyte was greatly enhanced by the above-mentioned treatments. An increase up to two orders of magnitude was achieved for the room temperature conductivity. The conductivity increased by addition of nanograins more than can be ascribed to the changes in crystallinity. Nanograins interacted with anions and reduced the brittleness of the gamma-irradiated electrolyte.
