Dielectric analysis of Polystyrene polymer film

in this work an attempt has been made to study the various dielectric parameters of polystyrene film. The dielectric constant έ , dielectric loss έ and loss tangent tan δ have been determined in the frequency range (1 - 1 OOO)KHz at different temperatures. The frequency dependent conductivity σ was also measured to characterize the polymer. The complex impedance plot (cole-cole plot) was used to calculate the static dielectric constant έ , infin itely large frequency dielectric constant έ and relaxation times. Finally the results are analyzed in terms of different parameter .
