纳米摩擦发电机的发展为缓解能源危机提供了一种新的思路。本研究提出了一种基于熔融共混挤出法制备的具有良好服装相容性的低成本热塑性聚合物薄膜的柔性TENG，可用于收集人体运动产生的低频机械能。通过改性、原位化学氧化聚合和方便的浸涂，制备的TENG具有优异的耐湿性。在周期性运动的触发下，该装置可用于对商用电容器和200多个绿色LED进行充电，其输出功率密度达到2.06 W/m2。实验证明，该装置对人体运动能量的提取具有实用性。特别是以手轻敲为例，开路电压和短路电流分别高达340.8 V和73.7 μA，表明具有优异耐磨性的热塑性聚合物薄膜适合用于TENG作为高相对湿度环境下智能服装的电源。
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/m2after 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.
