Abstract: In this study, metal-semiconductor Zn@ZnO coreshell particles were prepared by the heat treatment of raw Zn powder under air atmosphere, and the prepared Zn@ZnO particles were incorporated into poly(vinylidene fluoride) (PVDF) to obtain high dielectric permittivity polymer. The results indicate that the Zn@ZnO particles remark ably increased the dielectric constant of the PVDF compos…
