A composite of polystyrene (PS)/ferroelectric barium stannate titanate (BST) with different BST concentration was prepared. The dielectric properties were measured using HP low impedance frequency analyzer. It is found that samples behaved as an RC network. Composites become more capacitive than resistive with increasing frequency while resistance decreases with increasing BST ceramic concentration. Temperature effects were monitored throughout the annealing process. It is found that the capacity and the ac conductivity increased after annealing while the bulk resistance decreased. Our results suggest that, the obtained material is expected to be a promising candidate for electronic ceramics. The study provides a better understanding of the relationship among these parameters.
