Abstract

Lead titanate (PT)/vinylidene fluoride-trifluoroethylene (P(VDF-TrFE)) copolymer 0-3 composites have been fabricated by solution blending followed by compression-molding. In order to obtain piezoelectric and pyroelectric activities the composites have been polarized by a stepwise poling method. Samples with (i) polarization in the ceramic phase only and (ii) parallel polarization in the ceramic and copolymer have been prepared. The piezoelectric and pyroelectric coefficients of these two types of composites have been measured and the results are discussed
