Thoroughly researching liquid-solid contact electrification can significantly enhance our understanding of liquid energy harvesting, chemical processes, and geological mechanisms. However, this research is challenging because liquid changes dynamically, the interface chemistry is complex, and there are few rapid and simple measurement methods available. In this study, a liquid-solid triboelectric nanogenerator was developed as a probe to successfully quantify the charges with varying polarities at the liquid-solid interface. Owing to the design of two spatially arranged electrodes, this proposed probe was able to quantify the interfacial charges within a mere 50 ms propelled by the significant electrical potential difference between the liquid and the electrodes. By concomitantly analyzing the charge signal and short-circuit current signal, the probe is utilized for detecting the flow state of the liquid. Finally, the probe has been demonstrated to be applicable for liquid energy harvesting. This study presents a promising approach to address the challenges of liquid-solid contact electrification research and provides a novel perspective for enhancing our understanding of the chemical processes at liquid-solid contact electrification.

用于在液-固界面定量研究电荷的摩擦电荷分离探针

深入研究液固接触带电可以显着增强我们对液体能量收集、化学过程和地质机制的理解。然而,这项研究具有挑战性,因为液体动态变化,界面化学复杂,并且几乎没有快速简单的测量方法。在这项研究中,开发了一种液-固摩擦纳米发电机作为探针,成功地量化了液-固界面上具有不同极性的电荷。由于设计了两个空间排列的电极,该探针能够在短短 50 毫秒内量化由液体和电极之间的显着电势差推动的界面电荷。通过同时分析充电信号和短路电流信号,探头用于检测液体的流动状态。最后,该探针已被证明适用于液体能量收集。这项研究提出了一种有前途的方法来应对液固接触带电研究的挑战,并为加强我们对液固接触带电化学过程的理解提供了一个新的视角。
