Abstract
We present a method to dissolve carbon nanotubes that simultaneously allows to prepare n-doped films. These films are composed of thinner bundles of longer tubes when compared to films prepared using surfactants and sonication. Their negative Seebeck coefficient and high electrical conductivity make them good candidates for thermoelectric applications. We investigate their stability in air by aging them at elevated temperatures, showing stabilities over 500 h, which is further improved by the use of crown ethers. Finally, we demonstrate the usefulness of the prepared materials by fabricating an organic thermoelectric generator comprising 40 legs.

Summary
1.7 nm n-doped in this way was found to be unstable, degrading within minutes upon exposure to air,6 which warrants further investigation. Doped mixtures of semiconducting and metallic tubes have shown good stability, which seemed to further improve with increasing CNT diameter.5 somewhat disappointingly, the electrical conductivity of thin films of semiconducting SWCNTs with a diameter of less than
