Abstract

The oil leakage on the ocean leads to the inevitable and critical environment crisis, indicating the self-powered alerts with the high sensitivity are rather crucial for the early detection, as well as for extended periods with low consumption. Inspired by the ramie leaf, we fabricated an electrospinning fiber polytetrafluoroethylene (EF-PTFE) film, and prepared a rolling pendulum-based triboelectric nanogenerator (RP-TENG) detector with the EF-PTFE surface, whose fiber morphology can realize the distinguishable interaction between oil and water, leading to different charge transfer. Besides, the compressible structure of EF-PTFE film can enhance the effect on the induced charge, thereby improving the TENG output. The open-circuit voltage (VOC) can increase from approximately 11 V to 15 V. Moreover, the absorption to the trace oil contributes to the high sensitivity, even the diesel concentration below 0.01 mL/m² on the water surface can be well detected. The RP-TENG can also identify petroleum and its derivatives. Furthermore, the TENG sensors with distinguishable absorption also can be extended to the detection of the trace chemicals, promoting the significant applications in multi-functional sensing.

海洋石油泄漏导致了不可避免的严重环境危机,这表明具有高灵敏度的自供电警报器对于早期检测和长期低耗而言至关重要。受苎麻叶的启发,我们制作了一种电纺丝纤维聚四氟乙烯(EF-PTFE)薄膜,并利用 EF-PTFE 表面制备了一种滚动摆式三电纳米发电机(RP-TENG)探测器,其纤维形态可实现油和水之间的可区分相互作用,从而导致不同的电荷转移。此外,EF-PTFE 薄膜的可压缩结构可增强对感应电荷的影响,从而提高 TENG 的输出。开路电压(VOC)可从约 11 V 提高到 15 V。此外,对痕量油的吸收也有助于实现高灵敏度,即使水面上的柴油浓度低于 0.01 mL/m²,也能很好地检测到。RP-TENG 还能识别石油及其衍生物。此外,具有可分辨吸收特性的 TENG 传感器还可扩展到痕量化学品的检测,从而在多功能传感领域得到广泛应用。

期刊介绍: Nano Energy is a multidisciplinary, rapid-publication forum of original peer-reviewed contributions on the science and engineering of nanomaterials and nanodevices used in all forms of energy harvesting, conversion, storage, utilization and policy. Through its mixture of articles, reviews, communications, research news, and information on key developments, Nano Energy provides a comprehensive coverage of this exciting and dynamic field which joins nanoscience and nanotechnology with energy science. The journal is relevant to all those who are interested in nanomaterials solutions to the energy problem. Nano Energy publishes original experimental and theoretical research on all aspects of energy-related research which utilizes nanomaterials and nanotechnology. Manuscripts of four types are considered: review articles which inform readers of the latest research and advances in energy science; rapid communications which feature exciting research breakthroughs in the field; full-length articles which report comprehensive research developments; and news and opinions which comment on topical issues or express views on the developments in related fields.
