The development of triboelectric nanogenerators (TENGs) which can be utilized to transform small and irregular energy into electricity provides a new idea to alleviate the serious energy crisis. In this study, a type of flexible TENG based on cost-effective thermoplastic polymeric nanofiber membranes fabricated via melt-blending extrusion method with good compatibility to garment had been proposed, which could be used to harvest the low-frequency mechanical energy produced by human motions. In the presence of modifications, in-situ chemical oxidative polymerization and facile dip-coating, the prepared TENG exhibited excellent humidity-resistance. Triggered by periodic motions, the device which could be applied to charge the commercial capacitor and more than 200 green LEDs revealed a high output power density of 2.06 W/m² after introducing polyaniline. The practicability of the obtained device to scavenge the energy of body motions had been successfully proved. Especially with hand tapping as an example, the open-circuit voltage and short-circuit current reached up to 340.8 V and 73.7 μA respectively, which indicated that it is suitable for thermoplastic polymeric nanofiber membranes with outstanding wearability to be employed in TENGs to be a power supply for the smart garment under a high relative ambient humidity.

摩擦电纳米发电机（TENGs）的发展可以用来将不规则的小能量转化为电能，为缓解严重的能源危机提供了新的思路。在这项研究中，提出了一种基于高性价比热塑性聚合物纳米纤维膜的柔性TENG，该膜通过熔融共混挤出法制备，与服装具有良好的相容性，可用于收集人体运动产生的低频机械能。 。在改性，原位化学氧化聚合和容易的浸涂的存在下，制得的TENG显示出优异的耐湿性。在周期性运动的触发下，可用于给商用电容器充电的设备和200多个绿色LED表现出2.06 W / m ²的高输出功率密度引入聚苯胺后。已经成功证明了所获得的装置消除身体运动能量的实用性。特别是以手敲击为例，其开路电压和短路电流分别达到340.8 V和73.7μA，这表明它适用于具有优异耐磨性的热塑性聚合物纳米纤维膜，可用于TENG中。在较高的相对环境湿度下为智能服装供电。
