Title: | Electrical conductivity enhanced dielectric and piezoelectric properties of ferroelectric 0-3 composites | Authors: | Wong, CK Shin, FG |
Issue Date: | 15-Mar-2005 | Source: | Journal of applied physics, 15 Mar. 2005, v. 97, no. 6, 064111, p. 1-9 | Abstract: | We have investigated the effects of electrical conductivity of the constituents on the dielectric and piezoelectric properties of ferroelectric 0-3 composites. The time-dependent internal electric fields are first derived, which can be induced by an applied ac field in dielectric measurement or stress in piezoelectric measurement. Our previously developed model [C. K. Wong, Y. M. Poon, and F. G. Shin, J. Appl. Phys. 90, 4690 (2001)] has been extended to include the additional contribution from the electrical conductivities and the frequency of measurement, which can be significant for ceramic/polymer composites possessing high conductivity in the matrix phase. The model provides an explanation to the surprisingly high piezoelectric d₃₃values reported by, e.g., Chen et al. [Sens. Actuators, A 65, 194 (1998)]. Explicit expressions for the transient and steady-state responses are given and the effective permittivity, d₃₃, d₃₁, and d[sub h] coefficients have been derived. | Keywords: | Lead compounds Filled polymers Ferroelectric materials Electrical conductivity Permittivity Transients Piezoelectric materials |
