Abstract:
Frequency dependences of the real and imaginary parts of the dielectric permittivity of films prepared from cyano-ethyl ester of poly(vinyl alcohol) have been studied within a frequency range of 25 Hz to 1 MHz at temperatures from 266 to 323 K. The frequency dependence of the total conductivity of the polymer dielectric has been calculated. At $T < T_g$, it has been established to follow a power law course with an exponent close to unity, which evidences hopping pattern of the conductivity. The anomalous increase of the dielectric losses and dielectric permittivity in the low-frequency range at $T\ge T_g$ is attributed to formation of double electric layers at the electrode-polymer boundary.
