Abstract

Textiles are an integral part of daily life globally, but their widespread use leads to significant waste generation. Repurposing these discarded fabrics for energy harvesting offers a sustainable solution to both energy demand and textile waste management. In this study, Textile-based Triboelectric Nanogenerators (T-TENGs) were developed using recycled cloth as tribopositive layers and polyvinyl chloride (PVC) film as the tribonegative layer, with aluminum foil tape serving as electrodes. Five different recycled textiles were evaluated, and Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray Spectroscopy (EDS) analysis revealed a correlation between yarn structure and carbon content, leading to enhanced triboelectric performance. Silk-based TENG (S-TENG) demonstrated the highest output, with 320.76 V and 8.73 µA, while exhibiting stable performance over 10,000 cycles. Practical applications were explored by integrating T-TENGs into shoe insoles for energy harvesting during walking and jumping, with rayon-based TENG generating up to 208.52 V on a PVC coil mat. This work highlights the dual benefits of waste reduction and sustainable energy applications, making a compelling case for advanced technologies where recycled textiles function as frictional materials to harvest mechanical energy from human motion and convert it into electrical energy for use in flexible sensors and wearable devices.

废弃纺织品电气化：将织物废料转化为用于生物机械能采集的高性能三电纳米发电机。

纺织品是全球日常生活中不可或缺的一部分，但其广泛使用会产生大量废物。将这些废弃织物重新用于能源采集，为能源需求和纺织品废物管理提供了一种可持续的解决方案。本研究开发了基于纺织品的三电纳米发电机（T-TENGs），使用回收布料作为摩擦正极层，聚氯乙烯（PVC）薄膜作为摩擦负极层，铝箔胶带作为电极。对五种不同的回收纺织品进行了评估，扫描电子显微镜（SEM）和能量色散 X 射线光谱（EDS）分析表明，纱线结构与碳含量之间存在相关性，从而提高了三电性能。丝基 TENG（S-TENG）的输出功率最高，达到 320.76 V 和 8.73 µA，同时在 10,000 次循环中表现出稳定的性能。通过将 T-TENG 集成到鞋垫中，在行走和跳跃过程中进行能量收集，探索了实际应用，其中人造丝基 TENG 在 PVC 线圈垫上可产生高达 208.52 V 的电压。这项工作强调了减少废物和可持续能源应用的双重好处，为先进技术提供了令人信服的理由，即回收纺织品可作为摩擦材料，从人体运动中收集机械能，并将其转化为电能，用于柔性传感器和可穿戴设备。
