“…They disclosed that electromagnetic fillers have additional effect in the piezoelectric performance of the PVDF polymer‐based nanogenerator as these fillers influence crystalline phase of the PVDF and interfacial polarization between the PVDF polymer and nanofiller. NiFe 2 O 4 /PVDF‐HFP electrospun nanocomposite‐based piezoelectric nanogenerator has also been reported by this research group . In this study, they have observed that PVDF‐HFP/NiFe 2 O 4 based nanogenerator can generate 4 V. It is also highlighted that nickel ferrite helps to improve the thermal and dielectric properties of the PVDF‐HFP polymer.…”

A unique potassium sodium niobate (KNN)/zinc oxide (ZnO) incorporated Poly(vinylidene fluoride) (PVDF) polymer-based hybrid piezoelectric nanogenerator has been developed by using electrospinning process.Electrospinning method has been used due to its remarkable role in improving the piezoelectric performance of the nanocomposite based nanogenerator by providing mechanical stretching and in situ poling of both the polymer as well as filler at the same time. The PVDF/KNN/ZnO electrospun nanocompositebased piezoelectric nanogenerator exhibits the maximum output voltage as compared to PVDF/KNN and PVDF/ZnO based nanogenerator. The output voltage and current for the PVDF/KNN/ZnO based nanogenerator are 25 V and 1.81 μA (when pressure is applied by the finger tapping mode) and 8.31 V and 5 μA (when pressure is applied by standard sewing machine). The synergistic effect of KNN and ZnO nanorods into PVDF polymer matrix significantly improves the resultant piezoelectric performance of the PVDF/KNN/ZnO based nanogenerator by which it has been possible to glow an LED, power density of 11.31 μW/cm 2 (finger tapping) and 10.38 μW/cm 2 (pressure applied by sewing machine). Finally, the practical applicability of the produced nanogenerator has been checked by attaching it on elbow and wrist of a human hand, which shows 90 mV (for elbow), 400 mV (front side of wrist), and 225 mV (back side of wrist) output voltage by bending and moving of the same.

“…Not only artificial polymers [30] and biopolymers [31,32] can be used for the production of nanofiber mats, but also polymers mixed with non-soluble materials can be used for electrospinning [33,34]. By adding particles, it is also possible to produce magnetic nanofiber mats for various applications [35][36][37]. These magnetic nanofibers are promising for basic research and future applications in spintronics or neuromorphic computing [38][39][40][41][42].…”

Electrospun Carbon Nanofibers from Biomass and Biomass Blends—Current Trends

et al. 2021

In recent years, ecological issues have led to the search for new green materials from biomass as precursors for producing carbon materials (CNFs). Such green materials are more attractive than traditional petroleum-based materials, which are environmentally harmful and non-biodegradable. Biomass could be ideal precursors for nanofibers since they stem from renewable sources and are low-cost. Recently, many authors have focused intensively on nanofibers’ production from biomass using microwave-assisted pyrolysis, hydrothermal treatment, ultrasonication method, but only a few on electrospinning methods. Moreover, still few studies deal with the production of electrospun carbon nanofibers from biomass. This review focuses on the new developments and trends of electrospun carbon nanofibers from biomass and aims to fill this research gap. The review is focusing on recollecting the most recent investigations about the preparation of carbon nanofiber from biomass and biopolymers as precursors using electrospinning as the manufacturing method, and the most important applications, such as energy storage that include fuel cells, electrochemical batteries and supercapacitors, as well as wastewater treatment, CO2 capture, and medicine.

Piezoelectric nanogenerators (PENG) with flexible and simple design have pronounced significance in fabricating sustainable devices for self-powering electronics. This study demonstrates the fabrication of electrospun nanocomposite fibers from polyvinylidene fluoride (PVDF) filled Zinc Oxide (ZnO)/Iron Oxide (FeO) nanomaterials. The nanocomposite fiber based flexible PENG showed piezoelectric output voltage of 5.9 V when 3 wt.% of ZnO/FeO hybrid nanomaterial was introduced, which was 29.5 times higher than the neat PVDF. No apparent decline in output voltage was observed for almost 2000 seconds attributed to the outstanding durability. This higher piezoelectric output performance is correlated with the β-phase transformation studies from the Fourier transformation infrared spectroscopy and the crystallinity studies from the differential scanning calorimetry. Both these studies show respective enhancement of 3.79 and 2.16 % in the β-phase crystallinity values of PVDF-ZnO/FeO 3 wt.% composite. Higher dielectric constant value obtained for the same composite (3 times higher than the neat PVDF) confirms the increased energy storage efficiency as well. Thus the proposed soft and flexible PENG is a promising mechanical energy harvester, and its good dielectric properties reveals the ability to use this material as good power sources for wearable and flexible electronic devices.
