This work reports a facile method to create efficient natural textile based triboelectric nanogenerators (N-TENGs). First, plain natural textiles, cotton and silk, were dip-coated in cyanoalkyl silane and fluoroalkyl silane to transform their surface energy into positive and negative triboelectricity. The N-TENGs were fabricated by stacking an cyanoalkylated siloxane grafted fabric with an fluoralkylated siloxane grafted fabric to assemble a Cu fabric electrode. A single N-TENG generated a maximum output voltage and output current of 216.8 V and 50.3 μA (0.87 μA cm-2), without any nanopatterning. The double stacked N-TENG showed an enhanced output current of 84.8 μA (1.46 μA cm-2), and exhibited a maximum power output of 0.345 mW cm-2 at an external resistance of 0.42 MΩ. In addition, the N-TENG can light up 100 light-emitting diodes (LEDs) and charge capacitors, demonstrating its self-powering applications.
这项工作报道了一种简便的方法来制造高效的基于天然纺织品的摩擦纳米发电机（N-TENGs）。首先，将普通天然纺织品棉和丝绸浸涂在氰基烷基硅烷和氟烷基硅烷中，以将它们的表面能转化为正摩擦电和负摩擦电。通过将氰基烷基化硅氧烷接枝织物与氟烷基化硅氧烷接枝织物堆叠以组装铜织物电极来制造N-TENGs。单个N-TENG在没有任何纳米图案化的情况下产生的最大输出电压和输出电流分别为216.8 V和50.3 μA（0.87 μA cm-2）。双层堆叠的N-TENG显示出增强的输出电流84.8 μA（1.46 μA cm-2），并且在0.42 MΩ的外部电阻下表现出0.345 mW cm-2的最大功率输出。此外，N-TENG可以点亮100个发光二极管（LED）并为电容器充电，展示了其自供电应用。
