“…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.

“…On the other end, ferroelectric polymers become more attractive for its exceptional mechanical stability but they offer very low dielectric and piezoelectric properties. Hence the combined properties of ferroelectric ceramic and polymers are desirable for many practical applications [2,[6][7][8].…”

Polymeric piezoelectric composites for energy harvesting applications are considered a significant research field which provides the convenience of mechanical flexibility, suitable voltage with sufficient power output, lower manufacturing cost, and rapid processing compared to ceramic‐based composites. This review focuses majorly on the basic theory and principles behind piezoelectric energy harvesting (PEH) devices, followed by specified materials used for the different devices. Different structural configurations associated with fabrication of PEH devices are discussed in detail along with their major advantages and drawbacks. Numerous classes of piezoelectric polymers such as polyvinylidene fluoride, polylactic acid, cellulose, polyamides, polyurea, polyurethanes, and their composites used for energy harvesting applications as a productive alternative of lead‐based piezo‐ceramics, are extensively addressed and explored. Additionally, current global and Indian scenarios associated with PEH devices, major challenges associated with them, and the future perspective of such devices are also reported in this review.

“…Ferroelectric polyvinylidenfluorid (PVDF) [7,8], its copolymer with hexafluoropropylene [9], as well as nonferroelectric substances such as polyimide [10], polyurethane [11], polytetrafluoroethylene [12], polyvinyl chloride [13], polybenzoxazol [14] and epoxy polymers [15,16,17] are most often used as a matrix in composite systems. Nanodisperse BaTiO 3 [7,8,9,17,18], Pb(Zr,Ti)O 3 (PZT) [14,15,19] and Ba(Fe 0.5 Nb 0.5 )O 3 [20,21] are most often used as a ferroelectric filler.…”

The high dielectric constant ferroelectric-polymer nanocomposite was developed for producing the heat-resistant and chemical stable planar layers. According to the composite coatings formation conditions, the following value ranges of dielectric constant and loss factor were received: 30–400 for dielectric constant and 0.04–0.1 for loss tangent, accordingly. Unlike of composite components, the obtained composite material is characterized by thermo-stability of electrical parameters up to 250 °C. The dielectric frequency spectra of the composite exhibit two clearly visible peaks in contrast to the spectra of the polymer and ferroelectric ceramics. The developed composite material can be used as a built-in film capacitors material in microelectronic devices.
