“…Ramasundaram et al introduced a novel technique of fabricating highly sensitive piezoelectric force sensors [ 134 ]. Pre-prepared 96% β-phase electrospun PVDF nanofiber mats were hot-pressed with AgNPs, followed by spin coating of polystyrene-block-polyisoprene-block-polystyrene (PS-b-PI-b-PS) block copolymer as shown in Figure 19 .…”

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.

“…[ 150 ] In another study by Ramasundaram et al., they demonstrated that annealing the electrospun PVDF nanofiber removed the residual solvent rapidly and thus increased the degree of crystallinity. [ 161 ] Moreover, they also believed the oriented polymer chains formed during electrospinning would not change its orientation state during annealing, and they enable an easy switching of dipoles that contributed to a good piezoelectric response. In general, as shown in Table 2 , annealing is a simple and effective method to enhance the ferroelectric phase content and is applicable to enhance the piezoelectricity of polymers.…”

Poly(vinylidene fluoride) (PVDF)‐based polymers demonstrate great potential for applications in flexible and wearable electronics but show low piezoelectric coefficients (e.g., −d33 < 30 pC N−1). The effective improvement for the piezoelectricity of PVDF is achieved by manipulating its semicrystalline structures. However, there is still a debate about which component is the primary contributor to piezoelectricity. Therefore, current methods to improve the piezoelectricity of PVDF can be classified into modulations of the amorphous phase, the crystalline region, and the crystalline–amorphous interface. Here, the basic principles and measurements of piezoelectric coefficients for soft polymers are first discussed. Then, three different categories of structural modulations are reviewed. In each category, the physical understanding and strategies to improve the piezoelectric performance of PVDF are discussed. In particular, the crucial role of the oriented amorphous fraction at the crystalline–amorphous interface in determining the piezoelectricity of PVDF is emphasized. At last, the future development of high performance piezoelectric polymers is outlooked.

“…The sensor shows a potential from 44° to 122° is 4.4 mV deg -1 at 76 mS [26]. Ramasundaram et al (2019) have prepared dodecylamine functionalized non polar silver NP on PVDF nanofiber for electrode to display a piezo-sensor which can be used for sensing forces on human skin and energy harvesting (Figure 6) [27]. They achieved highest -phase content (96 %) at optimized speed of 5000 rpm and 150 °C.…”

In this review, we have discussed on the latest development in metal nanoparticle composites based on PVDF via electrospinning process for electronic applications. Human robotics, wireless-data communication, nanogenerators, wearable biocompatible/bio-inspirable sensors, motion detectors, and actuators have become a key component in self-powered IoT devices. Due to the power demand, an urge is in the industry for fabricating portable, flexible, and sustainable green micro and nano devices. PVDF and its copolymers have attracted greater attention because of their excellent piezoelectric, dielectric, magnetic, and good mechanical properties, suitable for lightweight application and due to the biocompatible nature. Piezoelectric property can be enhanced with the addition of different metal nanoparticles and can be used for various application like sensor, actuators, energy harvesters, health monitors, EMI shielding. Interesting results reported by many research groups working in this field is consolidated in this review paper.
