Synthesis, NMR Characterization and Electrical Properties of Siloxane- Based Polymer Electrolytes.

Abstract

A crosslinked siloxane-based polymer has been prepared by the reaction of Poly(methylhudrosiloxane), monomethyl ether poly(ethylene glycol), and poly(ethylene glycol). The polymer, which has been structurally characterized by 29 Si NMR, forms complexes with LISO CF3 that exhibit good ionic conductivities (for a LiSO3CF3 15 wt% complex). The polymer and its salt complexes have been characterized by elemental analysis, 29 Si NMR powder diffraction X-ray powder diffraction, DSC, and AC complex impedance spectroscopy. The dependence of the ionic conductivity was investigated as a function of temperature, salt concentration (91 wt % to 25 wt %), and alkali metal cation (Li, Na, K, Rb, and Cs). Keywords: Polysiloxane, Polyethylene glycol, Copolymers, Polymer electrolytes, Polymer salt complexes, Ionic conductivity.
