“…The use of piezoelectric 0-3 composites for sensor applications has been extensively researched for a number of different polymer systems [3][4][5][6][7][8][9][10][11][12]. For this type of composite, mainly the thermoplastic ferroelectric polymer, poly-vinylidenefluoride (PVDF) [3][4][5][6][7][8][9][10] and thermosetting epoxy based resins [11,12] were used.…”

We report on the optimisation of a recently developed high performance 0-3 piezoelectric composite comprising of the piezoelectric Lead Zirconate Titanate (PZT) powder and a liquid crystalline thermosetting matrix polymer (LCT). The matrix polymer is a liquid crystalline polymer comprising of an HBA-HNA backbone with phenylethynyl end-groups. The use of a high performance polymer makes the composite a possible candidate to be used in sensor applications at elevated temperatures. The composite properties were optimised by calcining the PZT powder at different temperatures, prior to mixing the powders into the LCT matrix. The aim is to study the effect of the calcining temperature on the piezoelectric properties of the composite The PZT powders were characterised by X-ray diffraction and scanning electron microscopy. The dielectric constant and piezoelectric charge constant (d 33 ) of the composite samples was measured. It was found that a relationship exists between the calcining temperature of the PZT powder and the piezoelectric properties of the composites. A maximum voltage constant of g 33 =63 mVm/N was obtained for a composite containing 40% (by volume) of PZT powder calcined at 1150°C.

“…If PVDF and its copolymers are used as matrices, the conflict of piezoelectric constants can limit its advantages and result in lower output. Previous reports indicated that PZT/P(VDF-TrFE) 0-3 composites with 50 volume percent ceramic did not exhibit a piezoelectric response because they had the opposite sign piezoelectric coefficient, thus canceled out [57]. To circumvent this effect, different poling process can be adapted.…”

This chapter deals with the development of ferroelectric polymer polyvinylidene fluoride (PVDF)-based nanogenerators. Due to its inherent flexibility, PVDF has been studied for application in nanogenerators. We first introduce PVDF and its copolymers, and briefly discuss their properties. Then, we discuss fabrication methods, including solution casting, spin coating, template-assisted method, electrospinning, thermal drawing, and dip coating. Using these methods, a wide variety of ferroelectric polymer structures can be fabricated. In addition to the performance enhancements provided by fabrication methods, the performance of PVDF-based nanogenerators has been improved by incorporating fillers that can alter the factors affecting the performance. Next, we review energy sources that can be exploited by PVDF-based nanogenerators to harvest electricity. The abundant energy sources in the environment include sound, wind flow, and thermal fluctuation. Finally, we discuss implantable PVDF-based nanogenerators. Another advantage of PVDF is its biocompatibility, which enables implantable nanogenerators. We believe that this chapter can also be helpful to researchers who study sensors and actuators as well as nanogenerators.

“…Hence several attempts have been made to develop PZT polymer composites which combine much easier processing with a sufficient sensitivity and some ductility. Various PZT-polymer combinations have been explored including mostly PZT-PVDF systems [2][3][4][5][6][7][8] and PZT-epoxy systems [9,10] with moderate success. A major problem in developing composites with adequate properties is the substantial decrease in piezoelectric sensitivity of these systems which leads to a high minimal PZT volume fraction in order to achieve sufficient sensing or actuating characteristics.…”

Piezoelectric and mechanical properties of novel composites of PZT and a liquid crystalline thermosetting resin

2007

A novel series of lead zirconate titanate (PZT) ceramic-polymer composites has been developed and characterized. The matrix polymer is a liquid crystalline thermosetting resin (LCR) based on a HBA-HNA backbone and phenylethynyl end-groups. The composites show excellent high temperature processability. The dielectric properties were studied as a function of PZT volume fraction and processing conditions. Piezoelectric behaviour was compared to Yamada et al. model for 0-3 composites. For a moderate PZT volume fraction a high value for the piezoelectric stress constant of g 33 = 48 mV m/N was measured, which, in combination with a good chemical and thermal resistance of the polymer matrix, makes the material a good candidate for sensor applications at elevated temperatures. The liquid crystalline thermosetting character of the polymer imparts interesting high temperature post-formability.
