Sažetak
(PEO)8ZnCl2 polymer electrolytes and nano-composites were prepared using PEO -irradiated to dose of 529 kGy. The effect of -radiation from a Co-60 source were studied by small-angle X-ray scattering (SAXS) simultaneously recorded with differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD) at synchrotron ELETTRA. Above-mentioned treatment largely enhanced the conductivity of polymer electrolyte. Room temperature conductivity increase up to two orders of magnitude was achieved (1). Figure 1. DSC, WAXD and SAXS results for γ-irradiated polyelectrolyte (PEO)8ZnCl2 in the temperature range from 20°C to 100°C at rate of 1°C/min, a) showing the DSC heating and cooling cycle (denoted with DSC), b) showing evolution of the intensity of the strong WAXD line at 2 =19.21 (denoted with TH and TC), c) showing radius of gyration (RG) in the cooling cycle of SAXS (denoted with TC) and d) presenting RG in the heating cycle of SAXS (denoted with TH).
