Abstract:
Triboelectric nanogenerators (TENGs), being at the forefront of energy harvesting technologies, possess the ability to convert ambient energy sources into electrical power. However, the low energy density and non-recyclability of the tribolayers severely hinder its further application. To address this crucial issue, we propose an innovative approach by incorporating imine linkages into fluorine-containing polymers, creating a high-performance TENG with recyclability. The integration of imine linkages not only enhances the electrical output of TENG devices but also ensures their long-term sustainability as an energy solution. Notably, TENG devices utilizing this recyclable material demonstrate remarkable contact electrification performance, achieving a short-circuit current of up to 29.5 μA and an output voltage of up to 964 V. Furthermore, the efficient degradation and re-generation of the recyclable material facilitate a remarkable recovery of over 80% in the output of the refabricated TENG. To improve the energy utilization efficiency of the TENG, a power management circuit (PMC) based on a DC-DC buck converter is integrated to regulate the TENG without requiring an additional power supply. These findings offer crucial insights for advancing high-performance, recyclable TENG devices, which play a pivotal role in the development of sustainable energy harvesting technologies.
