“…PVDF-based membranes are extensively employed for different applications because of their high thermal and mechanical stability [10]. Researchers have recently observed that the introduction of semiconducting Zinc oxide (ZnO) in the PVDF matrix can significantly enhance the electrical properties of these polymer composites [11], because ZnO has a wide bandgap (3.37 eV), which makes it an efficient UV absorber with an absorption edge of about 368 nm. The stability of the electron-hole pairs is constant even at room temperature due to its large exciton binding energy (60 meV), which is much larger than the room-temperature thermal energy (26 meV) [12].…”

“…The Ni-coated PVDF-GO conductive polymer composite membranes were introduced and studied for wastewater solution [22]. Several chemical and physical methods have been employed for the synthesis of doped PVDF samples [11,17,19,22]. As reported in literature, different properties of polymer composites are strongly influenced by the type, density, distribution, and aspect ratio of the fillers [23,24].…”

Polymer composites are recently introduced as flexible candidates for modern electronic devices. Transition metals oxides incorporated PVDF polymer composite thin films were successfully synthesized and investigated for an optical response. The effect of ZnO and NiO nanoparticles as PVDF fillers is studied in this work. Experimentally pure and doped PVDF uniform and evenly distributed thin films were synthesized by sol-gel based spin coating method. Structural studies were carried out with X-ray diffraction analysis which reveals the sharp traces of ZnO and NiO and endorses the presence of crystalline fillers in PVDF polymer composite thin films. The Field emission scanning electron microscope was used to examine the surface morphology of prepared thin films containing a smooth, uniform distribution and compact polymer traces. Refractive index, extinction, absorption coefficient, reflectivity, optical conductivity and real epsilon were extracted using spectroscopic ellipsometry. Enhanced response of optical parameters was observed in nanoparticles containing PVDF polymer composites. The absorption coefficient seems to increase with the increment of nano-filler contents, which makes these materials suitable for photovoltaic applications. The maxima of the refractive index were recorded as 1.6 for pure PVDF and 2.1 for maximum nano-filler content with an incredible shift to higher energy values. The optical conductivity was observed to increase with the incorporation of nanoparticles in PVDF. The maximum values of real epsilon were recorded as 2.3 for pure PVDF and 3.9 for the highest nano-filler containing composition. The increasing trend of real epsilon in nano-fillers containing compositions is attributed to the enhanced polarization and storage capability of these composites. The outcomes of this work are considered that ZnO-PVDF-NiO advanced polymer composites are promising candidates for enhanced modern electronic devices.

“…[ 2,6–14 ] There are different classes of piezoelectric materials, such as ferroelectric ceramics [BaTiO 3 , lead zirconate titanate (PZT)], piezoelectric polymers [polyvinylidene fluoride (PVDF), poly(vinylidene fluoride‐trifluoroethylene) (P(VDF‐TrFE))], and piezoelectric composites that are made of ferroelectric ceramic filler embedded in the polymer matrix. [ 9,14–22 ] Piezoelectric composites are undoubtedly the most suitable materials for this application: they are able to combine the piezoelectric properties of the filler with the flexibility of the matrix, which makes them preferable relative to bulk ceramic. [ 12 ] Furthermore, they are characterized by a low poling electric field and high Curie temperature.…”

“…[ 11,28–30 ] Composites with 0–3 connectivity, which consist of homogeneously dispersed particles in the matrix, are the most commonly produced because of their simple fabrication. [ 22,30,31 ] Nevertheless, they exhibit low piezoelectric sensibility until they reach large volumetric contents. Only high filler contents lead to an increase in connectivity, and thus enhanced electric field distribution.…”

Piezoelectric soft material based on inorganic/organic composites suitable for aerospace and aeronautical monitoring sensors is fabricated. The designed material is a piezoelectric composite made of lead zirconate titanate (PZT) filler embedded in a poly(dimethyl siloxane) (PDMS) matrix. To improve the piezoelectric properties of the film, the connectivity of the ceramic filler is increased via electric field‐assisted structuration, which leads to columnar arrangement of the filler across the thickness. This structure (1–3) shows higher piezoelectricity than one with randomly dispersed filler (0–3). Piezoelectric and dielectric activities of PZT/PDMS in 0–3 and 1–3 configurations at different volume fractions are compared. The results confirm that the 1–3 connectivity leads to superior piezoelectric behavior. Thermal stability of electroactive properties and high temperature X‐ray diffraction (XRD) analyses are performed: the composites maintain a good piezoelectric response, even at 200 °C. Following a process optimization, the piezoelectric behavior of this new class of composites approaches the fluorinated ferroelectric polymers one, with the advantages of piezoelectric properties stability preserved at a higher temperature and a lower poling electric field. In conclusion, there is potential for the integration of the designed sensor in aircraft ball bearings for condition monitoring.

Depletion of fossil fuels and increase in pollution through chemical batteries trigger the development of self‐powered devices based on flexible piezoelectric nanogenerators. Biocompatible piezoelectric PVDF nanocomposites merged with piezoelectric fillers like ZnO, KNN, and BaTiO3 reproduce amended piezoelectric current, contributing to the safe application as biosensors and flexible industrial devices. Optimized loading, precise selection, and variating the surface chemistry of piezoelectric filler, along with fabrication schemes comprising different structural configurations of composites, considerably influence its potential for application as energy harvester. Also, optimized processing condition upgrades dielectric constant, energy storage density, and reduces dielectric loss, thereby plummeting energy dissipation even after prolonged usage. Consequently, this paper reviews the principles, properties, fabrication techniques, and market application of PVDF composites. A detailed relationship of significant electrical properties of PVDF composites with its fabrication methods and piezoelectric parameters of fabricated PVDF composites with reported real‐life wearable, implantable, and industrial‐based portable piezoelectric devices are discussed in detail along with tabulated data for clear understanding of structure‐property relationship. Again, market strategy for establishing flexible PVDF composite as a piezoelectric nanogenerator has been discussed. An in‐depth knowledge is provided for procuring affordable futuristic large‐scale PVDF‐based nanogenerators exhibiting affordable market worth.This article is protected by copyright.
