Dielectric characterization(complex electric modulus)of Na~+-ion conducting PEO/E8/NaIO4 salt-complexed polymer/liquid crystals composite

摘要

The frequency behavior(in the range 1 Hz-1 MHz)of the complex electric modulus of flexible films(150 μm-thick)of Na~+-ion conducting composite electrolyte produced from polymer poly(ethylene oxide)(PEO),nematic liquid crystals E8 and the salt NaIO4(in compositional ratio PEO:E8:NaIO4 = 63:27:10 wt),was studied by electrochemical impedance spectroscopy.Relaxation characteristics for the polymer/liquid crystal PEO/E8/NaIO4 composite were obtained,relevant to the applications of this ion-conducting dielectric material in flexible organic electronics and dielectric devices.
