“…There have been extensive studies on PZT based polymer composites with 0-3 connectivity [15][16][17][18][19][20][21][22][23][24][25][26][27]. Most of the studies dealt with the material properties of the films synthesized under the conditions which resulted in α rich PVDF phase.…”

“…The dielectric response of PZT-PVDF [15] composites were also studied over a wide range of temperature and frequency which helped to understand the relaxation mechanisms of PVDF under the influence of ceramic. Although, some work was carried out on PZT-PVDF composites [16][17][18][19][20][21], the role of PZT in the phase formation of PVDF was rarely mentioned in the literature.…”

The aim of the study is to find the role of lead zirconate titanate (PZT) in the phase formation of poly vinylidene fluoride (PVDF) and its effect on electrical and structural properties of PZT-PVDF composites (50 Vol%) with 0-3 connectivity. PZT particles of different sizes ranging from micron to nano are used. The particle size (<100 nm) were determined from TEM and the broadening of the characteristic diffraction peaks in the x-ray diffraction (XRD) pattern. Scanning electron microscopy (SEM), studies were performed to analyze the nature of ceramic particle distribution within the matrix. The percentage of polymer crystallinity was determined from differential scanning calorimetry (DSC) and found to decrease with decrease in ceramic particle size. The decrease in the crystallinity percentage is due the hindrance offered by ceramic during the crystallization of the polymer. The melting endotherms of the composites were deconvoluted and the amount of PVDF β-phase present in the composites were determined and was found to decrease with decrease in ceramic particle size. Fourier transform infrared spectroscopy (FTIR) studies were also carried out to confirm the decrease in the β-phase content with decrease in particle size. The variation in the amount of β-phase of the polymer is due to the presence of PZT which acts as a source of electric field during poling and converts other polymer phases to β-phase. The piezoelectric coefficient and remnant polarization was found to decrease with decrease in ceramic particle size and is due to the decrease in percentage of β phase in the composites.

“…The density values are calculated using the rule of mixtures [25,29] which is given by equation (1), ρ =ρ 1 (1−ф)+ρ 2 ф (1) where ф is the volume fraction of PZT. ρ 1 and ρ 2 is the density of polymer and ceramic phase respectively.…”

The 0-3 connected ferroelectric composites made of PZT and PVDF have been examined for its different physical and dielectric properties. The standard methods presented in earlier literatures for the composite preparation have been compared to find an effective method. The distinction in the physical properties like density and porosity of the piezocomposite was studied and their SEM morphological facts are scrutinized. The dielectric constant of PZT-PVDF composite has been predicted by using standard models and the results are compared. Also the relaxation behavior of polymer at higher temperature has been justified.
