Positron lifetime spectroscopy has been applied to study the temperature dependence of free-volume properties in a solvent-free polymer-salt complex polyethylene oxide (PEO) doped with ammonium iodide (NH 4 I, with NH / 4 /EO ร‰ 0.076) in the temperature range of 298-353 K. The observed lifetime spec
