Abstract

Hydrogel/PZT composite was prepared by encapsulating, Pb(Zr0.52Ti0.48)O3 (PZT) nanoparticles in an electroactive (PVA–PAA) hydrogel. The XRD studies confirmed the presence of pure tetragonal phase in PZT with crystallite size of 13 nm in the composite matrix. PZT nanoparticles were found to be embedded in the micro pores of PVA–PAA hydrogel as indicated by the SEM images. The composite shows three step degradation process in the TG/DTA measurements. Dielectric properties were studied from room temperature to 120 °C within wide frequency range of 100 Hz–600 kHz. At room temperature and intermediate frequency range, the composite shows a high dielectric constant of ~225 to 600 and low dielectric loss of 0.08.
