摘要

本文在 STENG 中引入了碳纤维，并通过电气化-磨损耦合模型和电气化-磨损同步测试研究了碳纤维对电气化和磨损性能的耦合效应。结果表明，与不含碳纤维的 STENG 相比，含有 0.2 wt% 碳纤维的 STENG 的电压提高了 90.36%，磨损率降低了 26.73%。碳纤维通过增加聚合物层的电容来提高电压，并降低转移膜的覆盖率，从而减少转移膜引起的电压降低。同时，碳纤维增加了聚合物层的硬度，从而减少了耕蚀和点蚀。虽然碳纤维引起的静电力增加会加剧磨损，但这种加剧是轻微的，可以忽略不计。

Coupling effects of carbon fibers on the electrification and wear performance of sliding mode triboelectric nanogenerators

This paper introduces carbon fibers into STENG, and investigates the coupling effects of carbon fibers on electrification and wear performance through electrification-wear coupling models and electrification-wear synchronous tests. It is shown that compared to STENG without carbon fibers, STENG with 0.2 wt% carbon fibers exhibits a 90.36 % increase in voltage and a 26.73 % decrease in wear rate. Carbon fibers increase the voltage through increasing the capacitance of the polymer layer, and reduce the transfer film coverage and thus the voltage reduction induced by transfer films. Meanwhile, carbon fibers increase the hardness of the polymer layer and thus reduce plowing and pitting. Although the increase of electrostatic force caused by carbon fibers aggravates wear, the aggravation is slight and can be ignored.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
