As triboelectric nanogenerator (TENG) technology continue to evolve, its application in harsh environments has increasingly captivated the interest of researchers. However, current research on heat-resistant materials remains predominantly focused development tribo-negative materials, with scant attention given their equally crucial tribo-positive counterparts. In this study, polyimide (PI) material enhanced tribo-positivity is developed by integrating amide groups electron-donating effects into molecular chain. Furthermore, TENG devices based series PI have demonstrated an open-circuit voltage (VOC) 242 V, a short-circuit (ISC) 8.13 μA, and transferred charge (QSC) 117 nC. Notably, these also demonstrate capability efficiently generate electricity even under elevated temperature conditions. This work not only proposes potential design strategy for developing high-performance applicable TENGs, but markedly propels advancement robust energy-harvesting engineered operation at temperatures.
