The influence of preparation processes on the structure and electrical properties of piezoelectric lead zirconate titanate/poly(vinylidene fluoride) composites was investigated. Hot-press method can enhance obviously the piezoelectric and dielectric properties of piezoelectric lead zirconate titanate/poly(vinylidene fluoride) composites by reducing the void in piezoelectric composites and decreasing the interface defect between ceramic phase and polymer phase. The electric results of piezoelectric lead zirconate titanate/poly(vinylidene fluoride) composites prepared by hot-press treatment are greater than these treated by cold-press. The research results indicated that the optimum polarization time was 40 minutes, the optimum temperature was 100 C and the optimum polarization field intensity was 3 kV/mm.
