【 摘 要 】

Composite material prepared from polyethylene oxide (PEO) and polyvinylpyrrolidone (PVP) doped with Sodium (meta)periodate (NaIO4) salt was studied by complex impedance spectroscopy at room temperature. The polymers PEO and PVP were mixed in a weight ratio 70:30 %, and the concentration of the embedded NaIO4compound was 7.5 wt.%. The effect from NaIO4filler on the dielectric permittivity of the three-component mixed system was analyzed in the frequency range 0.1 Hz - 1 MHz. As compared with the two-component polymer host PEO/PVP, a distinctly enhanced electrical and dielectrical response and an increase of the value of dielectric constant of the polymeric (PEO/PVP):NaIO4composite were present. This suggests the potential of this material for soft electronics and applications such as solid electrolytes.
