摘要
摩擦纳米发电机(TENG)是一种利用摩擦起电和静电感应的耦合原理将机械能转换成电能的新型能量转化装置。本论文报道了一种通过对摩擦电极材料进行结构控制和表面化学修以提高TENG输出的新方法。研究结果表明,以聚丙烯(PP)纳米线为摩擦电极的TENG的输出性能受PP纳米线直径和长度的影响,其中PP纳米线直径100 nm和长度14μm时输出最大;同时,还发现电极的表面组成对摩擦纳米发电机输出也有很大影响,如通过全氟辛基三氯硅烷表面修饰后,输出最大开路电压和短路电流密度可分别达到1900V和19mA/m~2,与未经修饰的光滑PP膜组成的TENG相比,输出提高了100倍,可以点亮372个商用LED灯。最后,利用此TENG设计了一种自供电的温度传感器,依靠TENG提供的电荷驱动温度传感器,可以在室温到100oC适用,展现出广泛的应用前景。
We report a new method to fabricate a polypropylene(PP) nanowire array based triboelectric nanogenerator(TENG) with high output through structural control and surface functionalization for harvesting friction mechanical energy. Compared with the smooth PP film based TENG, after structural control and surface functionalization with a modifier of 1H,1H,2H,2H-perfluorooctyltrichlorosilane, the output is increased to a maximum open circuit voltage of 1900 V and a short circuit current density of 19 mA/m2, increased by more than 100 times than that of the flat PP film based TENG. This TENG can light up 372 commercial LEDs. Furthermore, a self-powered temperature sensor is designed, which shows great potential application in daily life.
