Abstract
The main aim of this research is to investigate the effect of salt concentration on the dielectric properties (AC (sigma (AC)), permittivity (E >'), dielectric loss (sigma aEuro(3)), and dielectric relaxation process) and melting behavior of polyethylene oxide (PEO)/CdCl2 complexes. The dielectric study was carried out over a frequency range 102-335 kHz and a temperature range 25-45A degrees C. The AC conductivity, permittivity and dielectric loss of the PEO/CdCl2 complexes increase with increasing salt concentration and temperature. Also, it was found that the addition of CdCl2 salt to PEO host reduced the melting temperature of PEO host. Dielectric results reveal that the relaxation process of these complexes is due to viscoelastic relaxation or non-Debye relaxation at room temperature. Additionally, it was found that relaxation behavior remained viscoelastic at different temperatures and salt concentrations.
