Abstract

Triboelectric nanogenerator (TENG) is a prospective energy harvesting technology, especially polymer-based TENG has achieved remarkable achievements. However, most polymer-based triboelectric layers suffer serious structural degradation and rapid decrease of charge density at high temperatures, which severely lowers the power supply capacity of TENG and definitely limits their applications in extreme environments. Herein, the antioxidants are introduced into liquid crystalline polyarylate (LCP) to fabricate thermally stable TENG and enhance its thermal oxidation resistance. The peak voltage of the resultant TENG is boosted to 73.6 V at 200 °C, which is 144.1% higher than the value at 25 °C, indicating the remarkably high-temperature enhancing effect on electrical output performance. Meanwhile, the high-temperature enhancing TENG (HTE-TENG) exhibited a peak output electrical power density of 1071.3 mW·m-2 under a 109 Ω load. This work provides a sustainable route for reliable energy devices and electronics to serve in potential applications, such as rescue work, personal protection, and extreme environments.

基于抗氧化液晶聚芳酸酯的高温增强摩擦电纳米发电机。

摩擦电纳米发电机（TENG）是一种极具发展前景的能量收集技术，尤其是聚合物基的摩擦电纳米发电机已经取得了令人瞩目的成就。然而，大多数聚合物基摩擦电层在高温下会发生严重的结构退化和电荷密度的快速下降，这严重降低了TENG的供电能力，这无疑限制了其在极端环境中的应用。本文将抗氧化剂引入液晶聚芳酸酯（LCP）中，制备热稳定的聚芳酸酯（TENG），提高其抗热氧化性。在200°C时，所得TENG的峰值电压提高到73.6 V，比25°C时的峰值电压高144.1%，表明其对电输出性能有显著的高温增强作用。同时，高温增强型TENG （te -TENG）在109 Ω负载下的峰值输出功率密度为1071.3 mW·m-2。这项工作为可靠的能源设备和电子设备提供了一条可持续的途径，可用于潜在的应用，如救援工作、个人保护和极端环境。
