This article focuses on the development of triboelectric nanogenerator (TENG) by utilizing advanced 2D nanomaterials with innovative design and easy fabrication method to achieve durable TENG high-power density improved cycling performance. Herein, we fabricated a layer-by-layer stacked vertical contact-separation (CS) mode TENG. In this unique design, incorporated thin film micron-sized Ti3C2Tx-MXene ultrathin sheets (TMSs) into polyethylene terephthalate (PET) based tribo-negative electrode. A tribo-positive layer was prepared integrating an optimized amount NaCl polyvinyl alcohol (PVA) matrix. After optimization both layers, TMS-TENG showed open-circuit voltage (Voc) ∼ 390 V, short-circuit current (Isc) 96 μA, power 6.66 W·m−2. The boosted performance is due synergistic effect TMSs, used as charge trapping electronegative side, impact NaCl:PVA impregnated electropositive side ultrathin-layered structures sandwiched TMS serve bifunctionally accumulation entity simultaneously, increasing separation high dielectric constant, thus overall output tested pressure sensor monitor different sensitive physiological movements human body. Further applications designed TMS-TENGs have been revealed powering more than 500 LEDs, electronic calulator, swiftly charging micro-capacitors direct power. By engineering electrodes, can gain insight specific role that TMSs play in enhancing TENGs. research provides new avenue for designing self-powered pressure/motion sensors robotics harvesting biomechanical energy electrical sustainable electronics.

Improved Electrical Output Performance of Cellulose‐Based Triboelectric Nanogenerators Enabled by Negative Triboelectric Materials

Small, Год журнала: 2023, Номер 20(19)

Опубликована: Дек. 10, 2023

Cellulose-based triboelectric nanogenerators (TENGs) have attracted widespread attention due to the low cost and environmentally friendly characteristics of cellulose. However, achieving high electrical energy output from these generators still presents significant challenges. Here, cellulose is dissolved-regenerated form a composite aerogel with specific surface area, in which cellulose-based composites excellent negative properties are developed by coupling rich 3D network structure regenerated aerogel, modified barium titanate, poly(vinylidene fluoride). The TENGs assembled materials exhibit an voltage 1040 V current 1.165 mA at external force 8 N frequency 4 Hz, outperforming all materials. In addition, stable capacity, no property degradation 100 000 contact-separation tests. enables them harvest human movement waterdrops, demonstrating their great application prospects wearable devices, harvesting self-powered sensors, other fields.
