Dielectric and Piezoelectric Properties of Various Ferroelectric Ceramic-Polymer Composites

A study has been carried out to understand the different ceramics and different polymers to prepare composite with 0-3 connectivity. This is purely a review study on ferroelectric materials. Dielectric and piezoelectric properties for various composites have been discussed. It is clear that there is always an increase in dielectric constant (ɛr) for an increase in volume fraction. The piezoelectric strain coefficient (d33) showed an increase in values to the increase in volume fraction of the various ceramic-polymer composites. There is no existence of steady pattern found in the voltage coefficient (g33) values. The values obtained for the above confirms the usage of composites in various applications discussed in the introduction.
