能量收集装置作为独立电源的基本组件，在现代便携式智能电子产品中具有很大的应用前景。在这方面，在将可持续的机械能转化为电能的摩擦电纳米发电机（T-TENG）中使用导电纺织品基底已经成为高效发电的替代选择。在这里，我们解决的T-TENG的电气性能的增强，采用化学表面界面工程聚二甲基硅氧烷（SIE-PDMS）层作为涂层上的高导电性Ni-Cu纺织品基板。PDMS表面的操作是在这项工作中，在原位两步反应离子等离子体处理进行顺序Ar和CF 4 + O-2等离子体的主要方法。结构观察发现，在适当的CF 4 + O-2等离子体处理后，F在SIE-PDMS上出现，从而通过有效的表面充电能力产生增强的输出产生，这归因于F的大电负性。我们预计，这种简单的制造方法可以促进高度可穿戴的自供电设备的发展。
Energy-harvesting devices as basic components of independent power sources are highly promising for use in modern portable smart electronics. In this regard, the use of conductive textile substrates in triboelectric nanogenerators (T-TENG) that convert sustainable mechanical energy to electricity has emerged as an alternative option for efficient power generation. Here, we address the enhancement of the electrical performances of T-TENGs by employing chemically surface interface-engineered polydimethylsiloxane (SIE-PDMS) layers as coatings on highly conductive Ni-Cu textile substrates. Manipulation of the PDMS surface is a major approach in this work, where in-situ two-step reactive-ion plasma treatments were conducted with sequential Ar and CF4 + O-2 plasmas. Structural observations identified the appearance of F on the SIE-PDMS after suitable CF4 + O-2 plasma treatment, thus yielding enhanced output generation by the T-TENG through efficient surface charging ability, which was attributed to the large electronegativity of F. We anticipate that this simple fabrication approach may facilitate the development of highly wearable self-powered devices.
