Abstract

Complex impedance data demonstrate that addition of 2.2.2-cryptand increases the conductivity of NaSO₃CH₃ in amorphous poly(ethylene oxide) (aPEO) but decreases that of NaSO₃CF₃ in aPEO. Vibrational spectroscopic and X-ray diffraction measurements indicate that the influence of 2.2.2-cryptand is to dissolve crystallites of NaSO₃CH₃ into the polymer phase. The decrease in conductivity for NaSO₃CF₃-aPEO upon addition of 2.2.2-cryptand correlates with the precipitation of a crystalline phase, presumably [Na:2.2.2][SO₃CF₃].
