The serious environmental pollution and energy crisis have become a global issue, which makes it a pressing task to develop sustainable and clean energy sources. There exists a large amount of renewable energy in the ocean; unfortunately, most resources are underutilized. In this work, we demonstrate a performance-enhancing rolling triboelectric nanogenerator (TENG) based on nano-micro-structured polytetrafluoroethylene (PTFE) films. The nano-micro structure on the PTFE surface can increase the effective contact area and enhance the triboelectric effect, which is beneficial to improve the output performance. As a result, the output voltage and output current are 25.1 V and 7.3 μA, respectively. We further investigate the effect of nano-micro PTFE concentration on the output performance. The TENG based on a 45% concentration of nano-micro PTFE presents the maximum output power. Furthermore, this TENG can effectively harvest water wave energy with various amplitudes and frequencies, which has the potential to harvest ocean energy for environmental monitoring.
严重的环境污染和能源危机已成为一个全球性问题，这使得开发可持续和清洁能源成为一项紧迫任务。海洋中存在大量可再生能源；不幸的是，大多数资源未得到充分利用。在这项工作中，我们展示了一种基于纳米微结构聚四氟乙烯（PTFE）薄膜的性能增强型滚动摩擦电纳米发电机（TENG）。PTFE表面的纳米微结构可以增加有效接触面积并增强摩擦电效应，这有利于提高输出性能。结果，输出电压和输出电流分别为25.1 V和7.3 μA。我们进一步研究了纳米微PTFE浓度对输出性能的影响。基于45%浓度纳米微PTFE的TENG呈现出最大输出功率。此外，这种TENG可以有效地收集各种振幅和频率的水波能量，具有为环境监测收集海洋能量的潜力。
