摘要: Abstract In this research, thin films of poly(ethylene oxide) (PEO) blend with lithium hexafluorophosphate ( LiPF 6 ) salt and ethylene carbonate (EC) as plasticiser carbon nanotube (CNT) filler, are prepared using solution casting method. The conductivity dielectric response the nanocomposite polymer electrolyte systems studied within broad frequency range 5 Hz–5 MHz a temperature 298–373 K. conductivity–temperature plots observed to be Arrhenius nature. behaviour is analysed permittivity e r i ), loss tangent tan δ electric modulus M samples. It that rises sharply towards low frequencies due electrode polarisation effects. maxima shifts higher height peak increases increasing temperature.
