A study of the temperature dependence of the electromechanical response of ferroelectric Lead Zirconate Titanate (PZT) ceramics at high electric fields (up to 1.3 kV /mm) is reported. Simultaneous measurements were performed of strain, electric field and polarisation to form a complete response map from room temperature up to 200C. An electrostrictive model is shown to provide an accurate description of the electromechanical response to high levels of induced polarisation and electric field. This provides a method for decoupling strain contributions from thermal expansion and polarisation changes. Direct measurements of electrostriction and thermal expansion, above and below the Curie temperature are reported. Electrostriction coefficients are shown to be temperature dependent in these ceramic materials, with different values above and below the Curie temperature.

“…Above the Curie temperature there is no remanent polarisation, so zero field strain in both directions reverts to a normal expansion on heating. The transverse measurements reported here therefore help to explain previous reports of negative thermal expansion in poled PZT ceramics [12,13].…”

Negative thermal expansion in functional materials: controllable thermal expansion by chemical modifications

Negative thermal expansion (NTE) is an intriguing physical property of solids, which is a consequence of a complex interplay among the lattice, phonons, and electrons. Interestingly, a large number of NTE materials have been found in various types of functional materials. In the last two decades good progress has been achieved to discover new phenomena and mechanisms of NTE. In the present review article, NTE is reviewed in functional materials of ferroelectrics, magnetics, multiferroics, superconductors, temperature-induced electron configuration change and so on. Zero thermal expansion (ZTE) of functional materials is emphasized due to the importance for practical applications. The NTE functional materials present a general physical picture to reveal a strong coupling role between physical properties and NTE. There is a general nature of NTE for both ferroelectrics and magnetics, in which NTE is determined by either ferroelectric order or magnetic one. In NTE functional materials, a multi-way to control thermal expansion can be established through the coupling roles of ferroelectricity-NTE, magnetism-NTE, change of electron configuration-NTE, open-framework-NTE, and so on. Chemical modification has been proved to be an effective method to control thermal expansion. Finally, challenges and questions are discussed for the development of NTE materials. There remains a challenge to discover a "perfect" NTE material for each specific application for chemists. The future studies on NTE functional materials will definitely promote the development of NTE materials.

“…The rhombohedral phase shows higher deformation than the tetragonal phase when the temperature increases. [ 53 ] This is more noticeable in 0–3 composites than in 1–3 composites. In other words, the lattice stability of the structured composites is higher, which is consistent with the fact that the d 33 coefficient declines with increasing temperature, as previously shown in Figure 10a.…”

Piezoelectric soft material based on inorganic/organic composites suitable for aerospace and aeronautical monitoring sensors is fabricated. The designed material is a piezoelectric composite made of lead zirconate titanate (PZT) filler embedded in a poly(dimethyl siloxane) (PDMS) matrix. To improve the piezoelectric properties of the film, the connectivity of the ceramic filler is increased via electric field‐assisted structuration, which leads to columnar arrangement of the filler across the thickness. This structure (1–3) shows higher piezoelectricity than one with randomly dispersed filler (0–3). Piezoelectric and dielectric activities of PZT/PDMS in 0–3 and 1–3 configurations at different volume fractions are compared. The results confirm that the 1–3 connectivity leads to superior piezoelectric behavior. Thermal stability of electroactive properties and high temperature X‐ray diffraction (XRD) analyses are performed: the composites maintain a good piezoelectric response, even at 200 °C. Following a process optimization, the piezoelectric behavior of this new class of composites approaches the fluorinated ferroelectric polymers one, with the advantages of piezoelectric properties stability preserved at a higher temperature and a lower poling electric field. In conclusion, there is potential for the integration of the designed sensor in aircraft ball bearings for condition monitoring.
