The electrical conductivity of thin films (150 μm) of composites produced from polymer poly(ethylene oxide) (PEO) and nematic liquid crystals E8 (in compositional ratio PEO:E8 = 70:30 wt%) was studied by means of complex electrical impedance spectroscopy in the range from 1 Hz to 1 MHz. Both ion conductivity and alternating-current conductivity of PEO/E8 films were determined as depending on temperature in the room-temperature region 25–50 ◦C. The results show that the ion-conductive PEO/E8 composite is a promising material for electronic applications.

Abstract

The electrical conductivity of thin films (150 μm) of composites produced from polymer poly(ethylene oxide) (PEO) and nematic liquid crystals E8 (in compositional ratio PEO:E8 = 70:30 wt%) was studied by means of complex electrical impedance spectroscopy in the range from 1 Hz to 1 MHz. Both ion conductivity and alternating-current conductivity of PEO/E8 films were determined as depending on temperature in the room-temperature region 25–50 ◦C. The results show that the ion-conductive PEO/E8 composite is a promising material for electronic applications.
