Poling study of PZT/P(VDF-TrFE) composites

Thick-film composites with 0.2 and 0.6 volume fractions of lead zirconate titanate (PZT) powder dispersed in a vinylidene-fluoride-trifluoroethylene copolymer [P(VDF-TrFE)] matrix were prepared by solvent casting followed by compression moulding. The composites were poled by various procedures to produce samples with only the ceramic phase poled, only the copolymer phase poled, or both the ceramic and copolymer poled. The polarization profiles of the poled composites have also been obtained using the laser intensity modulation method (LIMM)
