High Dielectric

Polymer-based composites with high dielectric constant and suppressed dielectric loss were successfully fabricated by using PZT@Ag core-shell structured particles as fillers and PVDF as polymer matrix. The PZT@Ag core-shell structured particles were synthesized via conventional solid-state method. The results indicate that the fillers dispersed in the polymer matrix prominently enhance the dielectric constant while keeping the dielectric loss unchanged simultaneously. Composites with high dielectric constant result from the high dielectric constant of PZT itself, the superior interfacial polarization of PZT@Ag core-shell structure and the conductivity of Ag according to percolation theory, while the dielectric loss is suppressed due to the tunneling current decreasing among Ag particles and Coulomb blockade effect.
