Practical application of triboelectric nanogenerators (TENGs) has been challenging, particularly, under harsh environmental conditions. This work proposes a novel 3D-fused aromatic ladder (FAL) structure as a tribo-positive material for TENGs, to address these challenges. The 3D-FAL offers a unique materials engineering platform for tailored properties, such as high specific surface area and porosity, good thermal and mechanical stability, and tunable electronic properties. The fabricated 3D-FAL-based TENG reaches a maximum peak power density of 451.2 µW cm at 5 Hz frequency. More importantly, the 3D-FAL-based TENG maintains stable output performance under harsh operating environments, over wide temperature (-45-100 °C) and humidity ranges (8.3-96.7% RH), representing the development of novel FAL for sustainable energy generation under challenging environmental conditions. Furthermore, the 3D-FAL-based TENG proves to be a promising device for a speed monitoring system engaging reconstruction in virtual reality in a snowy environment.
摩擦电纳米发电机（TENGs）的实际应用一直具有挑战性，特别是在恶劣的环境条件下。这项工作提出了一种新型的三维稠环芳香梯形（FAL）结构作为TENGs的摩擦正性材料，以应对这些挑战。三维FAL提供了一个独特的材料工程平台，可实现定制特性，如高比表面积和孔隙率、良好的热稳定性和机械稳定性以及可调电子特性。所制备的基于三维FAL的TENG在5Hz频率下达到了451.2µW/cm的最大峰值功率密度。更重要的是，基于三维FAL的TENG在恶劣的运行环境下，在很宽的温度（-45-100°C）和湿度范围（8.3-96.7%RH）内保持稳定的输出性能，这代表了新型FAL在具有挑战性的环境条件下用于可持续能源发电的进展。此外，基于三维FAL的TENG被证明是一种有前途的设备，可用于在雪地环境中进行虚拟现实重建的速度监测系统。
