PIEZOELECTRIC AND PYROELECTRIC PROPERTIES OF PT/P(VDF-TrFE) 0-3 COMPOSITES
نویسنده
چکیده
Lead titanate (PT)/vinylidene fluoride-trifluoroethylene (P(VDF-TrFE)) copolymer 0-3 composites have been fabricated by solution blending followed by conipression-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.

Pyroelectric Properties of PZT/P(VDF-TrFE) 0-3 Composites
0-3 composites of lead zirconate titanate particles dispersed in a polyvinylidene fluoridetrifluoroethylene copolymer matrix may have a good potential for pyroelectric sensor applications. Thermal expansion mismatch together with the piezoelectric activity of the constituents produces a secondary pyroelectric effect in a composite. A model for this secondary effect in 0-3 composites has been de...

In this study (0–3) P(VDF-TrFE)/BaTiO3 composites containing up to 60 vol% of ceramic phase were prepared by solvent casting or compression molding. Their thermomechanical, dielectric, and piezoelectric properties were investigated, and discussed in the light of the properties of the basic components, the processing route and the resulting morphology. The crystalline structure of the P(VDF-TrFE...
متن کاملMeasurement of the Piezoelectric Properties of Vinylidene Fluoride Oligomer Using Pneumatic Pressure for Tactile Sensors∗
Vinylidene fluoride [VDF] oligomer is a novel substance with a smaller number of VDF units and lower molecular weight than poly(vinylidene fluoride) [PVDF]. We previously reported that the piezoelectric coefficient of VDF oligomer was greater than that of vinylidene fluoride/trifluoroethylene copolymer [P(VDF/TrFE)], and that a film composed of VDF oligomer was thin and uniform. However, the pi...
متن کاملFerroelectric Properties and Polarization Switching Kinetic of Poly (vinylidene fluoride-trifluoroethylene) Copolymer
The discovery of the piezoelectric properties of poly(vinylidene fluoride) (PVDF) by Kawai [Kawai, 1969], and the study of its pyroelectric and nonlinear optical properties [Bergman et al., 1971; Glass, 1971] led to the discovery of its ferroelectric properties in the early 1970s. Since that time, considerable development and progress have been made on both materials and devices based on PVDF. ...

A model for the piezoelectric and pyroelectric activities of 0–3 composites of ferroelectric particles in a linear matrix has been developed based on the polarization behavior of the inclusions. The model is applied to simulate the piezoelectric activity of a lead zirconate titanate/epoxy system polarized under different fields and the piezoand the pyroelectric properties of lead titanate/ poly...
