Abstract
In this work we have evaluated the dielectric properties of Poly Vinylidene fluoride (PVDF) thin films of thickness (≈20 μm) as a function of temperature from 40–70° C and frequency varying from 500 Hz to 100 kHz respectively for Al‐Al and Cu‐Cu electrode configuration. The dielectric constant values increases with the increase in temperature. A broad peak is found at around (70±5)° C. The maximum value of dielectric constant and dielectric losses were attributed to the phase transition of the polymer. The variation in dielectric constant and loss tangent suggest the net effect of some internal field within the polymer along with the external A.C. field.
