Creating Thermally Stable P-Type Carbon Nanotubes Via Coordination Chemistry For Thermoelectric Materials
Carbon nanotube (CNT)-based thermoelectric (TE) materials have the potential to be used for the recovery of low-grade thermal energy. As TE devices are placed on heat sources, thermal stability of the materials-especially, retention ability of the doped states of CNTs- is one of the most important issues. Here, we show that the dopant selection via coordination chemistry allowed for establishing the stable p-doped CNTs lasting for more than 2 years at $100^{\circ} \mathrm{C}$ in air. Based on the less fluctuation of TE power factors of the doped CNTs, our results offer a promising avenue for creating CNT-based TE devices.
