Abstract

Abstract: PZT nano-power and PZT／P（VDF-TrFE）0-3composite have been prepared by so- l gel and hot -press methed respectively．Dielectric measurements of PZT／P（VDF-TrFE）0-3composite in frequency domain and time domain were carried out．Experimental results shown that the dielectric constant of composite increase with the volume fraction of PZT and appear a maxmum near the70％．Qualitative analyses of the results obtained in frequency domain were also present - ed．The results obtained in time domain indicate that there are three kinds of dielectric relaxation in PZT／P（VDF-TrFE）0-3composite．

Key words: multi-phase composite, PZT, dielectric relaxation, frequency domain, time domain
