“…Figure 6 compares the BDS and energy-storage performance of representative polymer matrix composites in recent years. [16,[44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62] As can be seen from the comparison in Figure 6, 0.7 vol% BNT-SST/P(VDF-HFP) nanocomposites has a higher electric field and energy-storage density, and the efficiency is up to 67.01%. In addition, 0.7 vol% BNT-SST/P(VDF-HFP) polymer matrix composites not only have excellent energy-storage performance but also have low raw material cost and relatively simple preparation process.…”

Polyvinylidene fluoride (PVDF) and its copolymers have been widely used in polymer‐based film capacitors due to their relatively high permittivity and electrical displacement compared with other polymers. Herein, poly(vinylidene fluoride‐hexafluoropropylene) (P(VDF–HFP)) is selected as the polymer matrix, and 0.5 (Bi0.5Na0.5)TiO3–0.5(Sr0.85Sm0.1)TiO3 (BNT–SST) nanoparticles are added as the filler into the polymer to prepare BNT–SST/P(VDF–HFP) nanocomposites. The microstructure, electrical properties, mechanical properties, and energy‐storage properties of the nanocomposites are investigated. The addition of BNT–SST nanoparticles improves the dielectric characteristics and breakdown strength of the nanocomposites. Particularly, when the BNT–SST filler content is 0.7 vol%, the highest breakdown strength reaches 545 MV m−1, which is 1.3 times higher than pure P(VDF–HFP). In addition, the insulation and mechanical properties of BNT–SST/P(VDF–HFP) composite films are improved. The highest direct current resistivity and Young's modulus obtained by 0.7 vol% BNT–SST/P(VDF–HFP) nanocomposites are 6.8 × 1013 Ω cm and 1.94 GPa, respectively. More importantly, at 545 MV m−1, the energy‐storage density and efficiency of 0.7 vol% BNT–SST/P(VDF–HFP) composites are 19.07 J cm−2 and 67.01%, respectively, which are better than other polymer matrix composites. These findings suggest that the addition of inorganic nanoparticles has important research implications for improving the energy‐storage performance of polymer‐based film capacitors.

Ceramics are considered intrinsically brittle at macro scale due to the lack of slip mechanism and pre-existing defects, which greatly limits their potential applications in emerging fields including wearable electronic devices and flexible display. In this contribution, we developed BiFeO 3 /SiO 2 dual-networks with exceptional flexibility through a coupled electronetting/electrospun method. The hybrid nanostructured networks endow the material with high tensile strength (2.7 MPa), excellent flexibility (80% recoverable deformation), and robust fatigue resistance performance (maintain flexibility after a 1000-cyclic compress test). After in-situ compounded with dielectric polymer via a layer-by-layer solution casting method, the resultant three-dimensional (3D) composite film exhibits a twice higher dielectric constant (ε r ) than polyether imide (PEI) film. More importantly, the breakdown strength of the 3D composite film is almost the same as that of the PEI film, resulting in an enhanced energy density of ~6.0 J/cm 3 and a high efficiency of 80% at 4.58 MV/cm. The unique structure, combined with the excellent balance between mechanical and dielectric properties in flexible structures, is of critical significance to the design of flexible functional ceramics and broadening their applications in wearable electric devices.

“…However, it is necessary to pay much more attention to the affinity of the material and thus check its mutual compatibility [78][79][80]. For example, there are efforts to improve ferroelectric and magnetic properties with BiFeO 3 [81][82][83][84], or also with the relatively popular BaTiO 3 to increase the β-phase [78,[85][86][87][88][89][90][91]. Other authors use ZnO to improve output voltage and improve crystalline structure [92,93].…”

A Brief Introduction and Current State of Polyvinylidene Fluoride as an Energy Harvester

This review summarizes the current trends and developments in the field of polyvinylidene fluoride (PVDF) for use mainly as a nanogenerator. The text covers PVDF from the first steps of solution mixing, through production, to material utilization, demonstration of results, and future perspective. Specific solvents and ratios must be selected when choosing and mixing the solution. It is necessary to set exact parameters during the fabrication and define whether the material will be flexible nanofibers or a solid layer. Based on these selections, the subsequent use of PVDF and its piezoelectric properties are determined. The most common degradation phenomena and how PVDF behaves are described in the paper. This review is therefore intended to provide a basic overview not only for those who plan to start producing PVDF as energy nanogenerators, active filters, or sensors but also for those who are already knowledgeable in the production of this material and want to expand their existing expertise and current overview of the subject.
