Resumo |
Variable-temperature four-probe conductivity measurements and Raman spectroscopy were investigated for iodine in poly(propylene oxide) (PPO) and NaI<sub>3</sub> in PPO. The Raman spectra indicate the presence of both triiodide and polyiodide species in samples of I<sub>2</sub>-doped PPO. The conductivity of these PPO/I<sub>2</sub> samples increased with increasing I<sub>2</sub> concentration and reached a plateau at approximately 12 vol % iodine. Raman spectra at 20 °C indicate that, at concentrations less than 23 vol % I<sub>3</sub>-, the dominant species is the triiodide. Polymer salt complexes with varying amounts of I<sub>3</sub>- appear to display a conductivity threshold near <i>T</i><sub>g</sub>, at 0.2 vol fraction of triiodide. |
