Polyphosphazene Electrolytes. 1. Preparation and Conductivities of New Polymer Electrolytes Based on Poly[bis(amino)phosphazene] and Lithium Perchlorate

Two series of new phosphazene polymer electrolytes, PPAP/LiClO4 and PHAP/LiClO4, were prepared by complexing lithium perchlorate, LiClO4, to poly(bis(pentylamino)phosphazene), PPAP, and poly(bis(hexylamino)phosphazene), PHAP, respectively. The electrolytes were characterized by the combination of FT...

Description
Summary:Two series of new phosphazene polymer electrolytes, PPAP/LiClO4 and PHAP/LiClO4, were prepared by complexing lithium perchlorate, LiClO4, to poly(bis(pentylamino)phosphazene), PPAP, and poly(bis(hexylamino)phosphazene), PHAP, respectively. The electrolytes were characterized by the combination of FTIR, 31P-NMR, and 13C-NMR spectroscopies. Films of these electrolytes showed good dimensional stability and ionic conductivity. The glass transition temperatures were determined by differential scanning calorimetry. The highest ionic conductivity, σ, was 7 orders higher in magnitude than the σ of its parent polymer and was similar to the σ of PEO at room temperature. The plots of ionic conductivity versus temperature for the polymer electrolytes were found to correspond to the Vogel−Tammann−Fulcher equation throughout the temperature range 30−100 °C.
