Sodium alginate (SA) and graphene oxide (GO) composite pellets are prepared by one step simple procedure. The composites are found to be thermally stable up to 220°C in nitrogen atmosphere. The composite was studied for impedance analysis with varying temperature ranging from room temperature to 170°C. Dielectric constant of the samples was measured using the impedance data using standard formulae. It was found that the dielectric constant of the composites is high at low frequencies which may be due to the contribution from all the dipoles responding to the applied signal. However, at high frequencies, may be due to non-participating dipoles, the dielectric constant of the composites is lower.
