Understanding of the triboelectric charge accumulation from the view of microcapacitor formation plays a critical role in boosting the output performance of the triboelectric nanogenerator (TENG). Here, an electrospun nanofiber-based TENG (EN-TENG) using a poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE)/MXene nanocomposite material with superior dielectric constant and high surface charge density is reported. The influence of dielectric properties on the output performance of the EN-TENG is investigated theoretically and experimentally. The fabricated EN-TENG exhibited a maximum power density of 4.02 W/m² at a matching external load resistance of 4 MΩ. The PVDF-TrFE/MXene nanocomposite improved the output performance of the EN-TENG fourfold. The EN-TENG successfully powered an electronic stopwatch and thermo-hygrometer by harvesting energy from human finger tapping. Moreover, it was utilized in smart home applications as a self-powered switch for controlling electrical home appliances, including fire alarms, fans, and smart doors. This work presents an effective and innovative approach toward self-powered systems, human-machine interfaces, and smart home applications.

用于智能家电的静电纺PVDF-TrFE / MXene纳米纤维毡基摩擦纳米发电机

从微电容器形成的角度了解摩擦电荷的积累在提高摩擦纳米发电机（TENG）的输出性能方面起着至关重要的作用。在此，报道了使用具有优异介电常数和高表面电荷密度的聚偏二氟乙烯-三氟乙烯（PVDF-TrFE）/ MXene纳米复合材料的电纺基于纳米纤维的TENG（EN-TENG）。从理论和实验上研究了介电性能对EN-TENG输出性能的影响。制成的EN-TENG的最大功率密度为4.02 W / m ²匹配的外部负载电阻为4MΩ。PVDF-TrFE / MXene纳米复合材料将EN-TENG的输出性能提高了四倍。EN-TENG通过从人的手指敲击中收集能量，成功地为电子秒表和温湿度计供电。此外，它还被用作智能家居应用中的自供电开关，用于控制家用电器，包括火灾报警器，风扇和智能门。这项工作为自供电系统，人机界面和智能家居应用提供了一种有效的创新方法。
