Boosting the output performance of triboelectric nanogenerators via some unique methods is always a meaningful way to speed up their commercialization. However, the available approach to boost performance is mainly restricted to one physics effect based and the basic research of boosting performance via mutual coupling effects is little research. Herein, a new strategy is creatively proposed based on charge traps from mutual coupling effects, generated from g-C N /MXene-Au composites, to further promote the output performance of triboelectric nanogenerator. It is found that photon-generated carriers coupling surface plasmon effect enables composites filled into tribo-material with visible light is an excellent value in boosting performance. The charge traps from mutual coupling effects for boosting performance are analyzed theoretically and verified by experiments. The output power of boosting-triboelectric nanogenerator (TENG) achieves a sixfold enhancement (20 mW) of normal TENG with polydimethylsiloxane (PDMS) in ambient conditions. This work provides a profound understanding of the working mechanism of mutual coupling effects boosting the performance of TENG and an effective way for promoting TENG output.
通过一些独特的方法提高摩擦电纳米发电机的输出性能，始终是加速其商业化的一种有意义的方式。然而，现有的提高性能的方法主要局限于基于单一物理效应，而通过相互耦合效应提高性能的基础研究较少。在此，基于g-C₃N₄/MXene-Au复合材料产生的相互耦合效应中的电荷陷阱，创造性地提出了一种新策略，以进一步提高摩擦电纳米发电机的输出性能。研究发现，光生载流子耦合表面等离子体效应使得填充有可见光的摩擦材料中的复合材料在提高性能方面具有优异的价值。从理论上分析了相互耦合效应中用于提高性能的电荷陷阱，并通过实验进行了验证。在环境条件下，增强型摩擦电纳米发电机（TENG）的输出功率比使用聚二甲基硅氧烷（PDMS）的普通TENG提高了六倍（达到20 mW）。这项工作为深入理解相互耦合效应提高TENG性能的工作机制提供了帮助，并为提高TENG输出提供了一种有效方法。
