“…To further improve the piezoelectric output of PVDF films, more additives besides BT were used for the electrospinning approach. For instance, recently, BT was combined with ZnO, SWCNT, or Gr [ 106 ]. ZnO, as well as BT, is an excellent piezoelectric material with quite high dielectric value.…”

With the increase of interest in the application of piezoelectric polyvinylidene fluoride (PVDF) in nanogenerators (NGs), sensors, and microdevices, the most efficient and suitable methods of their synthesis are being pursued. Electrospinning is an effective method to prepare higher content β-phase PVDF nanofiber films without additional high voltage poling or mechanical stretching, and thus, it is considered an economically viable and relatively simple method. This work discusses the parameters affecting the preparation of the desired phase of the PVDF film with a higher electrical output. The design and selection of optimum preparation conditions such as solution concentration, solvents, the molecular weight of PVDF, and others lead to electrical properties and performance enhancement in the NG, sensor, and other applications. Additionally, the effect of the nanoparticle additives that showed efficient improvements in the PVDF films was discussed as well. For instance, additives of BaTiO3, carbon nanotubes, graphene, nanoclays, and others are summarized to show their contributions to the higher piezo response in the electrospun PVDF. The recently reported applications of electrospun PVDF films are also analyzed in this review paper.

The technological development of piezoelectric materials is crucial for developing wearable and flexible electromechanical devices. There are many inorganic materials with piezoelectric effects, such as piezoelectric ceramics, aluminum nitride, and zinc oxide. They all have very high piezoelectric coefficients and large piezoelectric response ranges. The characteristics of high hardness and low tenacity make inorganic piezoelectric materials unsuitable for flexible devices that require frequent bending. Polyvinylidene fluoride (PVDF) and its derivatives are the most popular materials used in flexible electromechanical devices in recent years and have high flexibility, high sensitivity, high ductility, and a certain piezoelectric coefficient. Owing to increasing the piezoelectric coefficient of PVDF, researchers are committed to optimizing PVDF materials and enhancing their polarity by a series of means to further improve their mechanical–electrical conversion efficiency. This paper reviews the latest PVDF-related optimization materials, related processing and polarization methods, and the applications of these materials such as those in wearable functional devices, chemical sensors, biosensors, and flexible actuator devices for flexible micro-electromechanical devices. We also discuss the challenges of wearable devices based on flexible piezoelectric polymer, consider where further practical applications could be.

We report the piezoelectric, dielectric and dynamic mechanical features of nanohydroxyapatite (nHA) embedded ethylene-covinyl acetate (EVA)/millable polyurethane (MPU) elastomer blends. The EVA/MPU/nHA systems were prepared by two-roll milling followed by compression moulding. The piezoelectric features were probed by dynamic contact electrostatic force microscopy (EFM).The neat EVA/MPU blend was not found to exhibit ferroelectric properties. However, upon incorporation of nHA, butterfly loops of EFM amplitude signals as well as complementary hysteresis curves were obtained, confirming the introduction of ferropiezoelectric properties. The ferro-piezoelectric features were found to be improved with an increase in nHA loading which recorded highest signals for 8 parts per hundred parts of rubber (phr) loaded composites. The fabricated devices generated a peak voltage of 4.02 V and 4.89 V respectively with 6 phr and 8 phr nHA loaded composites. Electrical properties such as dielectric constant, volume resistivity and loss factor as well as dynamic mechanical properties were examined. The viscoelastic features of the systems support the reinforcing feature with filler loading. TEM analysis of the composites indicated a uniform distribution of filler particles in the blend matrix, complementing the observed ferro-piezoelectric, dielectric and dynamic mechanical properties. The simultaneous modulation of piezoelectric and viscoelastic properties is a preferred feature for fast-responsive dielectric elastomers for their applications in various piezoelectric devices.
