Triboelectric nanogenerators (TENGs) excel in converting mechanical energy into electrical energy and are recognized as the optimal solution for energizing wearable electronics. In this study, we fabricated TENGs based on electrospun polyvinylidene difluoride (PVDF)/silane-based hyperbranched polyester of 3rd generation (Si.HBP-G3) nanoweb blends (0–40 wt-% of Si-HBP-G3 w.r.t. PVDF content). In the TENG structure, PVDF-Si.HBP-G3 and non-woven fabric of thermoplastic polyurethane served as the tribonegative and tribopositive layers, respectively. Among the blended compositions, PVDF-Si.HBP-G3-30 wt-% resulted in substantial enhancement in the triboelectric peak-to-peak voltage (V_p-p) of 66.5 V compared to neat PVDF (12.9 V) and P-Si.HBP-G3-10 (21.2 V), 20 (39.7 V) and 40 wt-% (31.8 V) blends under a load of 9.8 N at 1 Hz frequency. These outcomes pave a promising path for the development of TENGs offering applications in sustainable energy generation and wearable healthcare monitoring systems.

摩擦纳米发电机 (TENG) 擅长将机械能转化为电能，被认为是为可穿戴电子设备供电的最佳解决方案。在本研究中，我们基于电纺聚偏二氟乙烯 (PVDF)/第三代硅烷基超支化聚酯 (Si.HBP-G3) 纳米纤维网共混物制造了 TENG（Si-HBP-G3 相对于 PVDF 含量为 0–40 wt%） 。在TENG结构中，PVDF-Si.HBP-G3和热塑性聚氨酯无纺布分别作为摩擦负层和摩擦正层。在共混组合物中，与纯 PVDF (12.9 V) 和 P-Si 相比，PVDF-Si.HBP-G3-30 wt-% 导致摩擦电峰间电压 ( V _p-p ) 显着提高，达到 66.5 V。 HBP-G3-10 (21.2 V)、20 (39.7 V) 和 40 wt-% (31.8 V) 在 1 Hz 频率、9.8 N 负载下混合。这些成果为 TENG 的开发铺平了一条充满希望的道路，可在可持续能源发电和可穿戴医疗监测系统中提供应用。
