Abstract
Nowadays, the liquid–solid triboelectric nanogenerator (L-S TENG) has gained much attention among researchers because of its ability to be a part of self-powering technology by harvesting ultra-low-frequency vibration in the environment. The L-S TENG works with the principle of contact electrification (CE) and electrostatic induction, in which CE takes place between the solid and liquid. The exact mechanism behind the CE at the L-S interface is still a debatable topic because many physical parameters of both solid and liquid triboelectric layers contribute to this process. In the L-S TENG device, water or solvents are commonly used as liquid triboelectric layers, for which their wettability over the solid triboelectric layer plays a significant role. Hence, this review is extensively focused on the influence of the wettability of solid surfaces on the CE and the corresponding impact on the output performance of L-S TENGs. The present review starts with introducing the L-S TENG, a mechanism that contributes to CE at the L-S interface, the significance of hydrophobic materials/surfaces in TENG devices, and their fabrication methods. Further, the impact of the contact angle over the electron/ion transfer over various surfaces has been extensively analyzed. Finally, the challenges and future prospects of the fabrication and utilization of superhydrophobic surfaces in the context of L-S TENGs have been included. This review serves as a foundation for future research aimed at optimizing the L-S TENG performance and inspiring new approaches in material design and multifunctional energy-harvesting systems.
如今,液固三电纳米发电机(L-S TENG)受到了研究人员的广泛关注,因为它能够通过收集环境中的超低频振动成为自供电技术的一部分。L-S TENG 利用接触电化(CE)和静电感应原理工作,其中接触电化发生在固体和液体之间。由于固体和液体三电层的许多物理参数都会对这一过程产生影响,因此 L-S 界面 CE 背后的确切机制仍是一个值得商榷的话题。在 L-S TENG 器件中,水或溶剂通常用作液态三电层,它们对固态三电层的润湿性起着重要作用。因此,本综述广泛关注固体表面润湿性对 CE 的影响以及对 L-S TENG 输出性能的相应影响。本综述首先介绍了 L-S TENG、导致 L-S 界面 CE 的机制、TENG 器件中疏水材料/表面的重要性及其制造方法。此外,还广泛分析了接触角对不同表面上电子/离子转移的影响。最后,还介绍了在 L-S TENG 中制造和利用超疏水表面所面临的挑战和未来前景。本综述为今后旨在优化 L-S TENG 性能的研究奠定了基础,并启发了材料设计和多功能能量收集系统的新方法。
