“…The measurement indicates that the silver layer on the sample generates an eddy current under the H ac and without H dc , which could generate the thermoelectric effect. Since PVDF is a kind of piezoelectric and thermoelectric material, a thermoelectric effect generates voltage at a certain heat . The H ac dependence of the ME voltage signal exhibits that ME voltage is only induced by the thermoelectric effect instead of ME effect.…”

“…Since PVDF is a kind of piezoelectric and thermoelectric material, a thermoelectric effect generates voltage at a certain heat. 14 The H ac dependence of the ME voltage signal exhibits that ME voltage is only induced by the thermoelectric effect instead of ME effect. Under the applied H dc , the induced magnetoelectric effect and the thermoelectric effect are distinguished by comparing the magnitude of the voltage generated by the thermoelectric effect.…”

Driven by the development of internet technology, higher requirements on information materials and data storage devices were demanded. To improve the work efficiency and performance of the new generation of information materials and data storage devices, the magnetoelectric (ME) coupling and storage mechanism of magnetoelectric composites deserve more attention. Here, we explored the influence of applied magnetic fields on the output voltage on a metal–insulation–metal (MIM) sandwich composite for realizing the magnetoelectric memory by experiments and modeling. It is found that the DC magnetic field ( H dc ) and the output voltage of the polyvinylidene fluoride film are linearly correlated. At a frequency of 1 kHz, the magnetoelectric voltage coefficient is 60.71 mV cm –1 Oe –1 , which is evidently larger than that of other film materials. From this work, we can conclude that the MIM sandwich composite could generate higher magnetoelectric voltage under the AC magnetic field ( H ac ) with higher frequency, which could be used as the magnetoelectric memory device, and provides significant support for improving the performance of magnetoelectric memory devices and the whole internet system.

“…Localized cooling enabled by wearable TECs can gradually take the place of conventional systems, which decreases climate warming and power cost (Kishore et al, 2019 ). Hu et al ( 2020 ) prepared polymer–inorganic nanohybrid film consisting of nickel nanowires evenly dispersed in PVDF matrix by solution mixing casting and compression molding. The electrical conductivity of the film raised as a function of Ni NW content while the optimal power factor reached 24.3 μWm −1 K −2 .…”

Though solar cells are one of the promising technologies to address the energy crisis, this technology is still far from commercialization. Thermoelectric materials offer a novel opportunity to convert energy between thermal and electrical aspects, which show the feasibility to improve the performance of solar cells via heat management and light harvesting. Polymer–inorganic thermoelectric nanocomposites consisting of inorganic nanomaterials and functional organic polymers represent one kind of advanced hybrid nanomaterials with tunable optical and electrical characteristics and fascinating interfacial and surface chemistry. During the past decades, they have attracted extensive research interest due to their diverse composition, easy synthesis, and large surface area. Such advanced nanomaterials not only inherit low thermal conductivity from polymers and high Seebeck coefficient, and high electrical conductivity from inorganic materials, but also benefit from the additional interface between each component. In this review, we provide an overview of interfacial chemistry engineering and electrical feature of various polymer–inorganic thermoelectric hybrid nanomaterials, including synthetic methods, properties, and applications in thermoelectric devices. In addition, the prospect and challenges of polymer–inorganic nanocomposites are discussed in the field of thermoelectric energy.

“…Furthermore, PVDF and its copolymers are biocompatible and non-biodegradable, making them ideal for pharmaceutical and biomedical applications, such as tissue engineering, where a long-term structural support is required (Lee et al, 2011;Tandon et al, 2018). Additionally, PVDF is commonly used to manufacture pipes and fittings (Ezrin, 2013), valves (Ayyaru et al, 2020), cathodes & anodes in Li-ion cell (Domínguez-Robles et al, 2017) or high purity semiconductor applications (Hu et al, 2020), among others. PVDF has already been used in the manufacturing of surgical meshes for hernia repair (Klinge et al, 2002) or for treating PFDs such as POP (Balsamo et al, 2018;Barski et al, 2017), which are available on the market under the name DynaMesh®.…”
