Preparation and Properties of PZN-PZT/PVDF Piezoelectric Composites Modified by Graphite

Abstract:

The graphite-modified PZN-PZT/PVDF composites were fabricated by hot-pressed process using PZN-PZT ceramic powder, PVDF and graphite powder. The effect of graphite content on the electrical properties of the piezoelectric composites was investigated. The results indicated that the piezoelectric constant d33 could be enhanced obviously by adding suitable content of graphite into the composites. When 0.8wt% graphite was added, the PZN-PZT/PVDF composites showed the excellent properties: σ=3.31×10-6S/m, εr=133, tanδ=0.066, Kp=0.228, Qm=22.8 and d33=40.6pC/N, which showed 28% higher than that of the composites without graphite.
