“…From the analysis, it is confirmed that the obtained results are in proximity with earlier studies and the structure of PZT is identified as a perovskite structure. It is also clear from the patterns that most intense reflection (110) occurs at 2θ~31.14 o , which is very close to the value mentioned in literature for pure PZT ceramic phase [6,[11][12][13]. The average grain size of ball milled PZT powder was found to be 0.017 µm (17 nm) which is calculated by using Scherrer formula.…”

PZT-PVDF composites were prepared using different particle size of PZT and a hot press apparatus has been used for making samples. The structural and compositional analysis of the composite sample was done by using Scanning Electron Microscope (SEM) and Energy Dispersive Analysis of X-rays (EDAX) respectively. The grain size of the ball milled PZT powder was analyzed using powder X-Ray Diffraction (XRD). The samples were poled at a fixed temperature for about an hour under different poling fields. The dielectric constant (ε r ) and the piezoelectric properties like piezoelectric strain coefficient (d 33 ) and voltage coefficient (g 33 ) of composite have been analyzed.

“…Nanocomposites also possess structural and electrical properties that can be tailored by controlling its composition to make them suitable for transducer applications. Piezoelectric PMNC consists of piezoelectric nanofillers like PZT, zinc oxide (ZnO) embedded in a polymer matrix (Daben 1990;Jain et al 2014;van den Ende et al 2007;Meyers et al 2013). These nanofillers impart piezoelectricity simultaneously retaining the properties of the polymer.…”

To satisfy the requirement of structural health monitoring (SHM) using light sensors with high sensitivity, novel large-area and flexible lead zirconate titanate (PZT)/polyvinyl-butyral (PVB)/ additives composite films were fabricated by the tape casting method. The microstructure and the piezoelectric and dielectric properties of the PZT/PVB/additives composite films were investigated systematically. Owing to the additives (dibutyl phthalate + castor oil), the flexibility and uniformity of the PZT/PVB composite films were improved significantly compared with conventional PZT/ PVB composite films. Moreover, the surfaces of the PZT/PVB/additives composite films are smooth and highly resistant to cracking. Scanning electron microscopy (SEM) was adopted to analyze the microstructure of the films. The microstructure analysis shows that microholes exist in the PZT/PVB composite films and an agglomeration phenomenon is noticeable. In contrast, PZT particles are well dispersed in the PVB matrix and there are few obvious microholes in the PZT/PVB/additives composite films. Furthermore, from energy-dispersive spectroscopy (EDS) results, it can be concluded that PZT particles were deposited at the bottom surface of the PZT/ PVB composite films. However, uniform deposition of PZT particles is achieved in the PZT/PVB/ additives composite films. In addition, owing to the additives, the improvement of the piezoelectric and dielectric properties of PZT/PVB/additives composite films is observed at a high volume fraction of PZT [φ (PZT) > 60%]. At φ (PZT) = 85%, the largest piezoelectric constant (d 33 ) reaches 44 pC/N, which is much higher than that of the reported PZT/PVDF films and PZT/PVB films. Moreover, the dielectric constant (ε r ) of the PZT/PVB/additives composite films (at room temperature and a frequency of 1 kHz) is higher than that of the PZT/PVB composite films with the same φ (PZT), and the dielectric loss (tanδ) is lower. Both the improved piezoelectric and dielectric properties are desirable for new piezoelectric sensor applications.
