Enhancement of Thermoelectric Performance of Single-Walled Carbon Nanotubes/Small Organic Molecule Hybrids by Fine-Tuning of the Alkyl Chain Length
Source abstract
Abstract
We investigated the alkyl chain length effect of small organic molecules (SOMs) on the thermoelectric (TE) efficiency and transport properties of single-walled carbon nanotubes (SWCNTs)/SOM hybrids. The SWCNTs/DBOBI with an octyl tethering chain exhibited the greatest Seebeck coefficient (91.6 ± 5.3 μV/K) and power factor (182.6 ± 15.1 μW/mK 2 ), revealing semiconducting-dominant carrier transport. The FeCl 3 -doped SWCNTs/DBOBI exhibited a significantly enhanced power factor of 236.2 ± 12.3 μW/mK 2 and a ZT of 0.021 at room temperature. Our study provides clear guidelines for enhancing the TE efficiency of SWCNT-based hybrid materials by systematically varying the alkyl chain length of SOMs.
