Abstract

Semiconducting single-walled carbon nanotubes (s-SWNTs) were extracted from SWNT mixtures using a flavin derivative (FC12). We evaluated the thermoelectric properties of the s-SWNT sheets. Electrical conductivity, power factor and figure of merit values of the sheets were increased by two orders of magnitude after removing FC12 simply by dipping in dichloromethane.
