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.

基于天然纺织物的摩擦电纳米发电机，用于有效的能量收集应用

这项工作报告了一种简便的方法来创建高效的基于天然纺织品的摩擦纳米发电机（N-TENGs）。首先，将普通的天然纺织品（棉和丝绸）浸涂在氰基烷基硅烷和氟代烷基硅烷中，以将其表面能转化为正摩擦和负摩擦电。N-TENG是通过将氰基烷基化的硅氧烷接枝织物与氟烷基化的硅氧烷接枝织物堆叠在一起以组装Cu织物电极而制成的。单个N-TENG产生的最大输出电压和输出电流为216.8 V和50.3μA（0.87μAcm ^-2），而没有任何纳米图案。双层N-TENG的输出电流提高了84.8μA（1.46μAcm ^-2），最大功率输出为0.345 mW cm ^-2外部电阻为0.42MΩ。此外，N-TENG可以点亮100个发光二极管（LED）和充电电容器，证明了其自供电应用。
