Flexible Thermoelectric Electrodes of the New Nitrogen-modified MXene/SWCNT Layered Structure Used for Low-grade Thermal Energy collection

Confronting the global challenge of energy efficiency in the backdrop of environmental concerns,the innovation of flexible thermoelectric electrodes marks a significant stride forward, especially in the realm of low-temperature heat recovery.This investigation unveils a pioneering electrode material, a nitrogen-doped SWCNT/MXene bilayer thin film, meticulously engineered for thermoelectric systems.Surpassing the conventional Pt electrodes, which are often hindered by their inherent inflexibility and prohibitive costs, our proposed electrodes have excellent ductility and good thermoelectric properties.At a modest temperature difference of 40°C, the thermopower output reaches 14.11µW cm -2 and the Seebeck coefficient rises to 1.61mV K -1 , significantly improving the thermoelectric performance significantly.This innovation not only positions itself as a formidable contender to Pt electrodes but also signals a new dawn for efficient thermoelectric energy harvesting, underscored by the material's scalability and ready availability.
