Frequency dependent dielectric parameters (ε′, ε″, tan δ) were measured in the range of 20 Hz to 2 MHz using the dielectric spectroscopy. A higher value of ε′ was attained and a corresponding relaxation peak in ε″ and tan δ appeared due to the electrode polarization in low frequency region for composite system.
