“…Compared to the neat polymer (Fig. 7a), all nanocomposites show higher output voltages substantiating the contribution of crystallinity and reinforcement from the filler particles [32,33]. The tri phasic filler combination showed high output voltages with the maximum of 2 V (Fig.…”

“…The dielectric constant, dielectric loss, tan δ and conductivity values of the samples were checked during the frequency range from 10 −2 to 10 6 Hz. Piezoelectric studies were done using an assembled set up consisting of a vibrating shaker, amplifier, frequency generator and accelerometer [32,33]. Specific weights were placed on the sample in such a way that variable forces were imposed on it in the transverse direction.…”

“…This increases the β-phase formation and in addition to this effect a stress induced polarization is also imparted by the external mechanical force [49]. This selfpolarization of semi crystalline polymer nanocomposite is responsible for the observed piezoelectric power generation and this material can be applied to fabricate self-powered devices such as nanogenerators [32]. Figure 7 shows the generated voltages at different frequencies of vibration for all the polymer nanocomposite samples.…”

“…For instance, with the electrospun fibers of PVDF-HFP/cobaltdoped ZnO system, we have obtained 2.8 V output performance recently [32]; however, in this work, simple solution mixing is adopted, which is the reason for the comparatively lower voltage. In all the composite films studied here, around 0.1 g of the sample (circular with 2 cm diameter and 0.2 mm thickness) was analyzed.…”

Integrating efficient energy harvesting materials in to soft, flexible, and eco-friendly substrates could yield significant breakthroughs in wearable and flexible electronics. Substantial advances are emerged in fabricating devices which can conform to irregular surfaces in addition to integrating piezoelectric polymer nanocomposites in to mechanical generators and bendable electronics. Here, we present a tri-phasic filler combination of one-dimensional titanium dioxide (TiO 2 ) nanotubes, twodimensional reduced graphene oxide, and three-dimensional strontium titanate (SrTiO 3 ), introduced in to a semi-crystalline polymer, poly(vinylidene fluoride-co-hexafluoropropylene). Simple mixing method was adopted for the composite fabrication after ensuring a high interaction between the various fillers. The prepared films were tested for their piezoelectric responses and mechanical stretchability. The results showed that the piezoelectric constant has increased due to the change in the filler concentration and reached a value of 7.52 pC/N at 1:2 filler combination. The output voltage obtained for the same filler composition was about 10.5 times that of the voltage generated by the neat polymer. Thus, we propose integration of these materials in fabricating energy conversion devices that can be useful in flexible and wearable electronics.

The effects of γ‐irradiation on the dielectric properties of stretched and poled polyvinylidene fluoride thin films synthesized by solvent cast method are reported. The films are subjected to γ‐irradiation with different doses (25, 50, and 75 kGy). XRD pattern is obtained to identify the presence of α/β phases. Dielectric constant and loss values of the stretched and poled films have been measured, before and after irradiation, and their nature of variation has been studied. β phase is retained even after the irradiation thereby confirming that the radiation damage is not significant. The dielectric loss is minimum in the frequency range 102 to104 Hz, giving the preferable frequency range of operation for devices

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.
