The triboelectric nanogenerator (TENG), based on triboelectrification and electrostatic induction, has been proven to be an ideal power supply device which converts all kinds of mechanical energy into electrical energy. However, high cost of fabrication and modification prevents wide application. In this work, we demonstrated a simple, cost-effective but efficient method, in which the friction pair materials, i.e., copper electrode and polydimethylsiloxane (PDMS), were both patterned by using sandpaper templates. The copper electrode and PDMS were patterned with sandpaper-like morphology and sandpaper-complementary-like morphology, respectively. Compared with TENG devices with nonpatterned or single-sided patterned friction layer, TENG devices with two-sided patterned friction layers have better output properties when the sandpaper templates used for the PDMS and copper electrode have the same large grit sizes (above 2000) because of closer contact and more sufficient friction. When the sandpaper templates used for the PDMS and copper electrode have the same grit size of 10 000, the maximum output short-circuit current density, open-circuit voltage, transfer charge quantity, and power density of as-prepared TENG devices are 3.89 mA/m², 200 V, 76 nC, and 4.36 W/m², respectively. Overall, patterning microstructure morphology and corresponding complementary morphology on the respective two sides of friction pair shows efficient improvement for the performance of the TENG device, providing a good guidance for its modification.

使用简单砂纸模板制备的具有双表面形状互补微结构的高性能摩擦电纳米发电机

基于摩擦带电和静电感应的摩擦电动纳米发电机（TENG）已被证明是一种理想的电源设备，可以将各种机械能转换为电能。然而，制造和修改的高成本阻碍了广泛的应用。在这项工作中，我们演示了一种简单，经济高效的方法，其中使用砂纸模板对摩擦副材料（即铜电极和聚二甲基硅氧烷（PDMS））进行构图。铜电极和PDMS分别以砂纸样形态和砂纸互补样形态构图。与带有无图案或单面图案摩擦层的TENG器件相比，当用于PDMS和铜电极的砂纸模板具有相同的大粒度时（2000年以上），由于接触更紧密，摩擦更充分，具有双面图案化摩擦层的TENG装置具有更好的输出性能。当用于PDMS和铜电极的砂纸模板的粒度为10000时，制得的TENG装置的最大输出短路电流密度，开路电压，转移电荷量和功率密度为3.89 mA /米²，200伏，76 NC，和4.36 W / M ²分别。总的来说，在摩擦副的两侧分别构图微结构形态和相应的互补形态，可有效提高TENG装置的性能，为TENG装置的改进提供了良好的指导。
