Thermal and electric properties of CeO2 nanoparticles dispersed in polyethylene oxide:NH4ClO4 complex

Abstract Nanoparticle inorganic filler ceria, CeO 2 is incorporated into polyethylene oxide (PEO)-NH 4 ClO 4 salt complex. Ceria nanoparticles improve the thermal stability of PEO salt composites. Two crystalline phases are found in thermal studies. Interfacial interaction of ceria with PEO is confirmed by the systematic variation of Fourier transform infrared spectra. The addition of ceria enhances the conductivity of PEO complex by one order of magnitude. The highest conductivity of 3.61 × 10 − 4  Scm − 1 is obtained for 25 wt.% CeO 2 .
