Frequency dispersion of the dielectric characteristics in polymer films based on the [NiSalen] complex

The results of the measurements of the dielectric properties exhibited by metal-containing polymer structures based on Ni(II) complexes in the frequency range f = 102–105 Hz are reported. It is established that, in the range of acoustic frequencies, the permittivity ε decreases with increasing frequency, whereas the dielectric loss tangent tan δ increases. At frequencies f > 104 Hz, the dependence tan δ(f) is characterized by a relaxation maximum. The possible mechanisms of dielectric polarization and charge transfer in an alternating-current electric field are considered.
