Résumé :

By means of experimental tools, we have studied the effect of lead zirconate titanate volume fraction introduced in polyamide-6/lead zirconate titanate composites on dielectric, piezoelectric, mechanical, and structural properties. As the first result, we found that the insertion of lead zirconate titanate particles makes the dielectric permittivity of the polyamide-6 matrix increases from 10 to 95.8. The dielectric property studies reveal that under an electrical field of 1 kV the remnant polarization is also increased from 0.17 to 0.4, this behavior is related to both the increase of volume fraction of lead zirconate titanate from 20% to 40% and the piezoelectric coefficient changes proportionally with that of volume fraction of lead zirconate titanate. Furthermore, piezoelectric activity increases with lead zirconate titanate particle size at a range where there is a lower order of magnitude. Finally, the uniform dispersion of the ceramic lead zirconate titanate particles in polyamide matrix has been confirmed by scanning electron microscopy analysis. The performances reached by polyamide-6/lead zirconate titanate composites open new horizons for energy harvesting and actuators.

Résumé :

Lead Zirconate Titanate (PZT) film was synthesized by sol-gel technique on a silicon substrate. The raw materials used to synthesize the solution of PZT consist of lead acetate, zirconate nitrate and titanate (IV) isopropoxide and 2methoxy ethanol is used as a stabilizer for Ti structure. Acetic acid is the solvent used to solve lat acetate and zirconate nitrate. The XRD pattern of the sample shows that the film has a tetragonal phase with a perovskite structure. FESEM revealed the surface morphologies and the cross-section of the film. The different thicknesses of film and annealing temperatures are investigated in this work. The dielectric constant was measured at 1 kHz, PZT films have a dielectric constant value ( 312-552 ) and a dielectric loss (0.02-0.08) at ambient temperature. Keywords: PZT film; Lead zirconated titanate; ferroelectric properties; dielectric constant.

Résumé :

Abstract Density of states and geometrical structures of modified Lead zirconate titanate are investigated using density functional theory within local density approximation. The electronic properties and bond length variation have been studied in terms of electronic structure and bonding mechanism principles respectively. Hybridization between Ti 3d - O 2p states and ferroelectric distortion have been addressed as a theoretical approach, to rule the improvement of ferroelectric properties of Lead zirconate titanate. The analysis of Ga, Tl modified Lead zirconate titanate were found to diminish the hybridization between Ti 3d - O 2p states, the relaxed behavior lead to the reversal of the known ferroelectric distortion. Y, Ho, Yb and Lu modified Lead zirconate titanate compounds have a tendency to intense the ferroelectric stability, its exhibit higher hybridization between Ti 3d - O 2p states than pure Lead zirconate titanate, also the arrangement of the ions distortions is strongly the same as the more favoured ferroelectric states of Lead zirconate titanate.

Résumé :

Although many kinds of flexible piezoelectric materials have been developed, there were few reports on flexible multifunctional nanofibers for energy harvesting. In this study, we prepared multifunctional nanofibers from lead zirconate titanate particles and shape memory polyurethane by electrospinning. The resulting nanofibers had both piezoelectric and shape memory effects. To improve the dispersion, lead zirconate titanate particles were modified by silane coupling agents. The lead zirconate titanate/shape memory polyurethane nanofibers were used to harvest energy from sinusoidal vibrations, and the lead zirconate titanate 80 wt% sample produced voltages of 120.3 mV (peak-to-peak). Taking advantage of the shape memory effect, the lead zirconate titanate/shape memory polyurethane nanofibers can be easily deformed into desired shapes and revealed the potential for realizing energy harvesting in complex structures.

Résumé :

We report on extended x-ray absorption fine structure (EXAFS) measurements for partially heat-treated gels in the lead zirconate titanate system (PZT). Self-consistent results obtained from the titanium and zirconium K-edges and the lead LIll-edge were used to determine bonding pathways between cations. For lead titantate (PT) and PZT gels, separate networks of predominantly Ti-O-Ti, Zr-O-Zr, and Pb-O-Pb linkages were observed. For lead zirconate (PZ) gels, both Zr-O-Pb and Zr-O-Zr linkages were observed. The results indicate heterogeneity at the molecular level. These findings are discussed in terms of the evolution of structure for PZT materials prepared by our sol-gel method.

Résumé :

The physical layering of sol-gel-derived lead zirconate titanate (PZT) 52/48 and lanthanum-doped PZT (PLZT) 2/52/48 on platinized silicon substrates was investigated to determine if the ferroelectric properties and fatigue resistance could be influenced by different layering sequences. Monolithic thin films of PZT and PLZT were characterized to determine their ferroelectric properties. Sandwich structures of Pt/PZT/PLZT/PLZT/PZT/Au and Pt/PLZT/PZT/PZT/PLZT/Au and alternating structures of Pt/PZT/PLZT/PZT/PLZT/Au and Pt/PLZT/PZT/PLZT/PZT/Au were then fabricated and characterized. X-ray photoelectron spectroscopy depth profiles revealed that the layering sequence remained intact up to 700 °C for 45 min. It was found that the end layers in the multilayered films had a significant influence on the resulting hysteresis behavior and fatigue resistance. A direct correlation of ferroelectric properties and fatigue resistance can be made between the data obtained from the sandwiched structures and their end-layer monolithic thin film counterparts. Alternating structures also showed an improvement in the fatigue resistance while the polarization values remained between those for PZT and PLZT thin films.

Résumé :

A photovoltage closed-loop servo control model of lead lanthanum zirconate titanate ceramic is proposed for a photovoltaic-electrostatic-driven system in this article. The control equations of the proposed servo control model are derived based on the mathematical model of lead lanthanum zirconate titanate with coupled multi-physics fields. The parameters of photovoltage of lead lanthanum zirconate titanate ceramic during the illumination phase and light-off phase are identified through the static experiment. Then, photovoltage response of lead lanthanum zirconate titanate ceramic with simple on–off control strategy is numerically simulated based on the control equations presented in this article. After that, the closed-loop photovoltage control experiment based on single lead lanthanum zirconate titanate ceramic is carried out. The simulation and experimental results show that the photovoltage can be successfully controlled by switching the ultraviolet light with an optical shutter. The control strategy can be applied in the photovoltaic-electrostatic-driven servo system to achieve the target degree of angular or displacement deflection. In addition, closed-loop photovoltage control experiment of lead lanthanum zirconate titanate bimorph irradiated by double ultraviolet light is carried out to equip the system with the capacity of reverse voltage output.

Résumé :

The subject of study was the growth and nucleation of sol-gel deposited lead zirconate titanate (PZT) films of composition Pb(Zr0_52,Ti0_4g)O3 (PZT52/48). This particular composition is on a phase boundary between titanium-rich tetragonally structured PZT and the zirconium-rich rhombohedral phase. The coexistence and relative instability of these phases is thought to be one of the origins of high piezoelectric coefficients exhibited by films of this composition. The aims of this study were to investigate variables affecting the piezoelectric coefficients in sol-gel deposited PZT52/48 thin films. Control of preferred orientation if PZT52/48 films on platinum-coated substrates was accomplished by manipulating processing conditions, specifically pyrolysis temperature. Corona poling was investigated as an alternative to contact poling. Attempts were made to find a set of poling parameters which yielded consistent results. Piezoelectric coefficients are highly dependant on poling conditions, with coefficient being lower in insufficiently poled films or those damaged by field induced sample cracking. It was observed that (001)/(100)-oriented samples with small grains had significantly lower piezoelectric coefficients and were harder to pole than coarser-grained (00l)/(l00)- oriented samples. Samples with a more irregular grain structure and a wide distribution of grain size had the lowest piezoelectric coefficients, irrespective of preferred orientation. The impact of grain size on piezoelectric coefficients was confirmed using the FWHM of the (200) reaction. Films with more irregular grain structures had higher FWHM than those with more uniform grains and had lower d33,f and e31,f. Values of e31,f and d33f were plotted against (001) intensity a determined from xray diffraction. It was difficult to determine any correlation between piezoelectric coefficients and (001) intensity. I comparison, there was a definite inverse correlation between d33,f, e31,f and FWHM, indicating that defect concentration has much more of an impact on piezoelectric coefficients in polycrystalline thin films than (001) intensity as a result of defect-induced domain pinning.

Résumé :

Lead-Zirconate-Titanate Pb(Zr,Ti)O₃ (PZT) based actuators are evaluated by automotive industry for advanced fuel-injection systems, including hydrogen injection. However, hydrogen can have deleterious effect on the PZT's functionality and properties. The general objective of this work is to study the interactions between PZT and hydrogen. The results of long-term (200-1200 hours) high-pressure (10 MPa) hydrogen exposure on the PZT microstructure show that hydrogen has only superficial effects on the microstructure of bare PZT. However, when an electrode is attached to PZT, the hydrogen damage increased; a porous layer developed immediately adjacent to the electrodes on the PZT surface due to hydrogen spillover. The kinetics of the PZT structural modifications due to hydrogen was investigated by online monitoring of the electrical properties of PZT above the Curie temperature, up to 650°C. The results show that the structural changes can be described by the classical nucleation and growth theory. The growth of the new structure appears to be limited by the diffusion of protons into PZT, with a calculated activation energy of 0.44± 0.09 eV, at 450-650°C. Two relaxation peaks were observed in the dissipation factor curves of the hydrogen-treated PZT. While the kinetics of one of the relaxation peaks obeys the classical Arrhenius law with the activation energy of 0.66 eV, the other peak shows an unusual relaxation kinetic. The mechanisms for the formation of these relaxation peaks are determined. Low temperature (20°C) diffusion of hydrogen into the PZT was also studied, using the water electrolysis technique. Based on the microstructural observations, the diffusion coefficient of hydrogen in PZT was calculated as 9×10-¹¹ cm²/sec. The Maxwell-Wagner polarization mechanism is determined to be responsible for the changes in the hydrogen-affected PZT capacitance. In the last part of the project, alumina coatings were applied to PZT plates using the sol-gel technique, to explore the possibilities of decreasing H₂ damage to PZT. The functionality of the coating against hydrogen damage was evaluated by the water electrolysis technique. Significant decrease of hydrogen damage was observed even for highly porous coatings. The mechanisms by which the alumina coating decreases the hydrogen damage were tentatively proposed.

Résumé :

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2008.
Includes bibliographical references (leaves 42-44).
Thus far, use of lead zirconate titanate (PZT) in MEMS has been limited due to the lack of process compatibility with existing MEMS manufacturing techniques. Direct printing of thin films eliminates the need for photolithographic patterning and etching, as well as allows for controlled deposition over non-planar topographies which cannot be accomplished with conventional spin coating processes. This thesis reports the optimal conditions of deposition and crystallization for high dielectric quality PZT thin films via thermal ink jet printing. Included are details of the solution chemistry developed, printing conditions required for MEMS quality films, and thermal processing parameters that enable a strong piezoelectric response.

Résumé :

Nanoscale ferroelectric materials have numerous possible applications such as actively tunable photonic crystals, terahertz emitters, ultrasound transducers, and energy harvesters. One of most technologically relevant ferroelectric materials is lead zirconate titanate (PZT) due to its large piezoelectric response. However, there are limited methods currently available for creating nanoscale PZT structures. Current top-down patterning methods include material removal via a high energy beam, which damages the piezoelectric's properties, and wet etching, which is an isotropic process that results in poor edge definition. Similarly, current bottom-up approaches such as hard template-growth and hydrothermal processing have limited control over the aspect ratio of the structures produced and lack site specific registry. In this work, a bottom-up approach for creating PbZr₀.₅₂Ti₀.₄₈O₃ nanotubes was developed using soft-template infiltration by a sol-gel solution. This method allows excellent control of the structures produced, overcoming current manufacturing limitations. PZT nanotubes were fabricated with diameters ranging from 100 to 200 nm, aspect ratios (height to diameter) from 1.25:1 to 5:1, and wall thicknesses from 5 to 25 nm. The piezoelectric and ferroelectric nature of the nanotubes was characterized via scanning probe microscopy in order to investigate nanoscale phenomena. Specifically, the effects of lateral constraint, substrate clamping, and critical size on the extrinsic contribution to the piezoelectric response were studied and the results are discussed.

Résumé :

In this paper, we demonstrate Lead zirconate titanate (PZT) nanofibers as a transducer to generate and detect ultrasound acoustic waves. PZT nanofibers with average diameter of 102nm were fabricated by the electrospinning method. The as-fabricated nanofibers were collected and aligned across a 10 μm silicon trench with Au electrodes. After annealing, the device was tested with the pulse/delay method. Two resonant frequencies, 8 MHz and 13MHz, were detected respectively. By using the Hamilton’s principle for coupled electromechanical systems with properly assumed mode shape, the resonant frequency was caudated. Base on the current testing result, a broadband ultrasound transducer was envisioned.

Résumé :

Lead Zirconate Titanate (PbZr1−xTixO3, PZT) is a high performance piezoelectric material which is widely used for making ultrasound transducers. However, pure PZT suffered from high acoustic impedance and crosstalk effect, which deteriorate their performances. To solve these problems, people developed micro fiber PZT composite. As restricted by the fabrication method, like dicing, the size of PZT micro fibers are usually on the order of 10s micros. In this paper, we are going to introduce a PZT nanotube composite, in which the size of active material is on the order of nanometers. To fabricate the PZT nanotube composite, we used a template assistant method. First an anodic aluminum oxide (AAO) template was made by two step anodic process. Then PZT nanotube composite was made by wetting the AAO template with PZT sol-gel. Following, top and bottom electrodes were made by silver paste. After fabrication, hysteresis loops were measured to verify the piezoelectricity property of this nanotube composite. Then the impedance of the composite transducer was measured by a network analyzer. Resonant frequency of the transducer was found by the impedance data. This nanotube composite based transducer could theoretically reduce or even eliminate the crosstalk effect, since the diameter of nanotube is much smaller than half wave length of ultrasound. So an improved performance of PZT nanotube composite based ultrasound transducer could be expected.
