Using Camellia oleifera shell as raw materials to preparative SiC ceramics by warm‐press forming and sintering is proposed in this paper. Warm‐press forming before preparing for the C. oleifera shell‐based SiC ceramics is beneficial to obtain the internal uniform and suitable pore structure of the cylindrical sample. Thermogravimetric analysis with differential scanning calorimetry was applied to analyze the pyrolysis behavior of C. oleiefra shell and phenolic resin. The scanning electron microscope and X‐ray diffraction were used to investigate the properties of C. oleifera shell‐based SiC ceramics. Then, the response surface method was applied to establish a multivariate prediction model based on the process parameters of warm‐press forming. And the regression equations of porosity and bending strength of COS‐SiC are obtained. The result demonstrated that the predicted and experimental values can be in good agreement for the model. By comparing the F‐value, it is found that the forming temperature and pressure during the process of warm‐press forming have a more significant influence on the porosity and bending strength of SiC ceramics. The optimization process parameters were obtained as follows: forming temperature 153°C, pressure 35 MPa, and holding time 30 min.

“…2 Since Wang Zhonglin began this creative research in 2012, 3,4 TENG has provided extensive applications in fields such as self-powered sensing, 5–8 clean energy harvesting, 9–12 intelligent wearable fabrics, 13–15 and air purification. 16–18 Using TENG as a power source to power electronic devices can effectively solve the problems of high cost and portability of traditional power generation methods. According to the relative displacement of the friction layer and the different device structures, TENG can be divided into four basic working modes: vertical contact separation mode, 19,20 horizontal sliding mode, 21,22 single-electrode mode, 23,24 and independent layer mode.…”

“…Polyvinyl alcohol (PVA) is one such economical and biodegradable synthetic polymer with potential applications in medical, textile, and food packaging industries [27,28]. Also, with its notable features, such as stability, flexibility, low cost, and better capability of film forming, PVA is considered as the suitable candidates for TENG fabrication [29][30][31][32]. Many researchers have used PVA as one of the tribopositive frictional layers for the fabrication of TENG.…”

Triboelectric nanogenerators (TENGs) have emerged as a promising alternative for powering small-scale electronics without relying on traditional power sources, and play an important role in the development of the Internet of Things (IoTs). Herein, a low-cost, flexible polyvinyl alcohol (PVA)-based TENG (PVA-TENG) is reported to harvest low-frequency mechanical vibrations and convert them into electricity. PVA thin film is prepared by a simple solution casting technique and utilized to serve as the tribo-positive material, polypropylene (PP) film as tribonegative, and aluminum (Al) foil as electrodes of the device. The dielectric-dielectric model is implemented with an arch structure for the effective working of the PVA-TENG. The device showed promising electrical output such as open-circuit voltage (VOC), short-circuit current (ISC), and power by using hand-tapping energy. Also, PVA-TENG is subjected to a stability test by operating the device continuously for 5000 cycles. The result shows that the device is mechanically durable and electrically stable. Further, the as-fabricated PVA-TENG is demonstrated to show feasible applications, such as charging two commercial capacitors with capacitances 1.1 and 4.7 μF, and powering green light-emitting diodes (LEDs). The stored energy in the 4.7 μF capacitor is utilized to power the humidity and temperature sensor without the aid of an external battery. Thus, the PVA-TENG facilitates ease of fabrication, robustness, and cost-effective strategy in the field of energy harvesting for powering lower-grid electronics by demonstrating their potential as a sustainable energy source.
