Abstract

The structure of polyethylene oxide doped with lithium perchlorate was studied. The macroscopic structure of the polymer-salt complexes was studied by thermal analysis and xray diffraction. The microscopic structure and polymer dynamics were studied by infrared, Raman and nuclear magnetic resonance spectroscopy. Thermal analysis and x-ray diffraction studies clearly revealed the change of crystalline phase to an amorphous phase by the addition of salt. The vibrational analysis showed a conformational transformation of the polymer chain by the addition of salt. Vibrational analysis also showed clearly the formation of free ion, ion-pair and salt cluster in the polymer as the concentration of the salt increased.
