Abstract

Skinner, et al. prepared PZT/polymer composites using the coral replamine process. The composites were found to have, for certain applications, greatly improved electromechanical and physical properties over those of conventional piezoelectric materials. However, the coral replamine process requires natural coral from the ocean as the starting replica material, making this process industrially unfavorable. This paper discussed PZT/polymer composites electromechanically and physically comparable to the Skinner replamine composites. Fabrication is simplified by the use of a compacted mixture of volatilizable plastic spheres and PZT powder, which when sintered yields a piezoelectric with a density of less than 2.9 g/cm3, a permittivity of ∼120 and a d33 of 180×10-12 C/N. The improved connectivity increases dh (hydrostatic) from ∼35×10-12 C/N (solid PZT) to 100×10-12 C/N.
