A triboelectric nanogenerator (TENG) has been thought to be a promising method to harvest energy from environment. To date, the utilization of surface structure and material modification has been considered the most effective way to increase its performance. In this work, a wrinkle structure based high-performance TENG is presented. Using the fluorocarbon plasma treatment method, material modification and surface structure are introduced in one step. The output ability of TENG is dramatically enhanced. After the optimization of plasma treatment, the maximum current and surface charge density are 182 μA about 165 μC m(-2). Compared with untreated TENG, the wrinkle structure makes the current and surface charge density increase by 810% and 528%, separately. X-ray photoelectron spectroscopy is employed to analyze the chemical modification mechanism of this fluorocarbon plasma treatment. Facilitated by its high output performance, this device could directly light 76 blue light emitting diodes under finger typing. The output electric energy could be stored then utilized to power a commercial calculator. As a result of the simple fabrication process and high output ability, devices fabricated using this method could bring forward practical applications using TENGs as power sources.
摩擦纳米发电机（TENG）被认为是从环境中获取能量的一种很有前途的方法。迄今为止，利用表面结构和材料改性已被认为是提高其性能的最有效途径。在这项工作中，提出了一种基于褶皱结构的高性能 TENG。使用氟碳等离子体处理方法，一步实现了材料改性和表面结构。TENG 的输出能力得到了显著提高。经过等离子体处理的优化，最大电流和表面电荷密度分别达到 182 μA 和 165 μC m(-2)。与未经处理的 TENG 相比，褶皱结构使电流和表面电荷密度分别增加了 810%和 528%。X 射线光电子能谱用于分析这种氟碳等离子体处理的化学改性机理。由于其高输出性能，该设备可以在手指打字时直接点亮 76 个蓝色发光二极管。然后可以存储输出的电能并用于为商业计算器供电。由于制造工艺简单和输出能力高，使用这种方法制造的器件可以为 TENG 作为电源的实际应用带来新的机会。
