“…Furthermore, less intense peaks existed at 44.0 and 45.6°, which resemble the (312) and (121) planes, respectively. A small shift in the main peaks in the case of the composite is due to tensile strain in the composite films . The additional characteristic peak present at 25.58° (denoted “#”) corresponds to the (002) lattice plane of graphitic carbon due to the inclusion of MWCNTs .…”

Flexible electronics have gained much interest, amplifying the need for advanced compact, lightweight, and bendable power sources. Present flexible supercapacitive energy-storage devices are restricted by poor mechanical properties, low cyclic stability, and small capacitance. Here, with state-of-the-art technology, cerium selenide nanopebbles are assembled with the aid of a controlled diffusive–capacitive mutualistic approach via a simple chemical method on multiwalled carbon nanotubes (MWCNTs) surfaces to design a hybrid nanostructure. The synthesized material has been well-characterized through structural, surface morphological, and elemental states by X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). Benefiting from diffusive–capacitive control, the unique hybrid supercapacitor (SC) electrode delivered an excellent storage capability of 451.4 F/g (@2 mA/cm2) maintaining 70.7% (@4000 cyclic voltammetry (CV) cycles) capacitance retention. More prominently, supreme mechanical bending of the designed solid-state supercapacitor in the symmetric configuration with the help of a poly(vinyl alcohol) (PVA)-LiClO4 gel electrolyte yields 86.9% retention at a bending angle of 175° with improved performance compared to a liquid-configured (84.1%@4000 cycles) supercapacitor maintaining a remarkable capacitance of 128.8 F/g (@2 mV/s) with high power density (2.8–5.6 kW/kg at energy densities of 36.3–14.5 Wh/kg).

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 shows piezoelectric output voltage of 5.9 V when 3 wt% of ZnO/FeO hybrid nanomaterial is introduced, which is 29.5 times higher than the neat PVDF. No apparent decline in output voltage is observed for almost 2000 s 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 (three 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.

Properties of novel 0–3 PZT/silicone resin flexible piezoelectric composites for ultrasonic guided wave sensor applications

et al. 2022

Ultrasonic guided wave (UGW) technology based on piezoelectric sensors is considered a very promising technology for aircraft structural damage detection. Traditional piezoelectric sensors are made of lead zirconate titanate (PZT) ceramics, but their brittleness and hardness make them difficult to apply to curved structure surfaces. In this study, a novel 0–3 flexible piezoelectric composite was fabricated by dispersing PZT particles in silicone resin, and its performance for potential applications in UGW sensors was studied. The effects of polarization conditions, PZT volume fraction, and PZT powder size on the performance of the composite were investigated. The influence of ambient temperature on composite performance was discussed, and temperature adaptability experiments were conducted. The results show that the optimal poling process of 0–3 PZT/silicone resin piezoelectric composite has a poling time of 25 min, a poling electric field of 4 kV/mm, and a poling temperature of 100°C. When the sensor is required to meet the test strain range of 8,000 με, the composite should be fabricated with a PZT volume fraction of 50% and a powder size of 170∼212 μm to obtain optimal sensing sensitivity. At an ambient temperature range of -55–75°C, the fabricated piezoelectric composite sensor has good flexibility and sensitivity in detecting the guide wave signals. These research results provide a new flexible piezoelectric sensing technology for aircraft structural damage detection.
