Abstract

Triboelectric nanogenerators (TENGs) are pivotal for powering small electronic devices by converting mechanical energy into electrical energy. However, the wear resistance of TENG friction layers remains a critical barrier to their long-term performance. This study introduces a hybrid material combining fluorinated ethylene vinyl ether (FEVE) and three-dimensional hierarchical porous graphene (3D HPG) to address these challenges. FEVE was selected for its low friction coefficient and excellent wear resistance, while 3D HPG enhances charge generation and transfer efficiency. The incorporation of 3D HPG into FEVE significantly improves both triboelectric output and durability, achieving a charge density of 140 μC/m², surpassing conventional copper-based TENGs (50-120 μC/m²). The hybrid material demonstrates minimal performance degradation over 10⁵ sliding cycles, highlighting its potential for durable, low-cost, and high-efficiency TENGs in wearable and portable electronics.

基于氟碳-石墨烯混合材料的高耐磨摩擦电纳米发电机。

摩擦电纳米发电机（TENGs）是将机械能转化为电能为小型电子设备供电的关键。然而，TENG摩擦层的耐磨性仍然是影响其长期性能的关键障碍。本研究介绍了一种结合氟化乙烯基醚（FEVE）和三维分层多孔石墨烯（3D HPG）的杂化材料来解决这些挑战。选择FEVE是因为其摩擦系数低、耐磨性好，而3D HPG则提高了电荷的产生和传递效率。在FEVE中加入3D HPG显著提高了摩擦电输出和耐用性，实现了140 μC/m2的电荷密度，超过了传统的铜基teng （50-120 μC/m2）。这种混合材料在105次滑动循环中表现出最小的性能下降，突出了其在可穿戴和便携式电子产品中耐用、低成本和高效的teng的潜力。

期刊介绍： Nanomaterials (ISSN 2076-4991) is an international and interdisciplinary scholarly open access journal. It publishes reviews, regular research papers, communications, and short notes that are relevant to any field of study that involves nanomaterials, with respect to their science and application. Thus, theoretical and experimental articles will be accepted, along with articles that deal with the synthesis and use of nanomaterials. Articles that synthesize information from multiple fields, and which place discoveries within a broader context, will be preferred. There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental or methodical details, or both, must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Nanomaterials is dedicated to a high scientific standard. All manuscripts undergo a rigorous reviewing process and decisions are based on the recommendations of independent reviewers.
