Since 2015, research on liquid-solid triboelectric nanogenerators (L-S TENGs) has shown steady growth, with the primary focus on application domains such as engineering, physics, materials science, and chemistry. These applications have underscored the significant attention L-S TENGs have garnered in areas like human-nature interaction, energy harvesting, data sensing, and enhancing living conditions. Presently, doping composite dielectric materials and surface modification techniques are the predominant methods for improving the power generation capacity of TENGs, particularly L-S TENGs. However, studies exploring the combined effects of these two approaches to enhance the power generation capacity of TENGs remain relatively scarce. Following a review of existing literature on the use of composite material doping and surface modification to improve the power generation performance of L-S TENGs, this paper proposes an experimental framework termed "self-assembled surface TENG@carbonyl iron particle doping (SAS-TENG@CIP)" to investigate the integrated power generation effects of L-S TENGs when combining these two methods. Research cases and data results indicate that, for TENGs exhibiting capacitor-like properties, the enhancement of power generation performance through composite material doping and superhydrophobic surface modification is not limitless. Each process possesses its own inherent threshold. When these thresholds are surpassed, the percolation of current induced by material doping and electrostatic breakdown (EB) triggered by surface modification can lead to a notable decline in the power output capacity of L-S TENGs. Consequently, in practical applications moving forward, fully realizing the synergistic potential of these methods necessitates a profound understanding of the underlying scientific mechanisms. The conclusions and insights presented in this paper may facilitate their complex integration and contribute to enhancing power generation efficiency in future research.
自2015年以来，液固摩擦电纳米发电机（L-S TENGs）的研究呈稳步增长态势，主要集中在工程、物理、材料科学和化学等应用领域。这些应用凸显了L-S TENGs在人与自然交互、能量收集、数据传感以及改善生活条件等领域受到的广泛关注。目前，掺杂复合介电材料和表面改性技术是提高TENGs发电能力的主要方法，尤其是对于L-S TENGs。然而，探索这两种方法结合以提高TENGs发电能力的研究仍然相对较少。在回顾了关于使用复合材料掺杂和表面改性来提高L-S TENGs发电性能的现有文献后，本文提出了一个名为“自组装表面TENG@羰基铁颗粒掺杂（SAS-TENG@CIP）”的实验框架，以研究这两种方法结合时L-S TENGs的综合发电效果。研究案例和数据结果表明，对于具有类似电容器特性的TENGs，通过复合材料掺杂和超疏水表面改性来提高发电性能并非没有限度。每个过程都有其固有的阈值。当超过这些阈值时，材料掺杂引起的电流渗透和表面改性引发的静电击穿（EB）会导致L-S TENGs的功率输出能力显著下降。因此，在未来的实际应用中，要充分发挥这些方法的协同潜力，就需要深入理解其背后潜在的科学机制。本文给出的结论和见解可能有助于它们的复杂整合，并为未来研究提高发电效率做出贡献。
