Abstract

Oxyethylene surfactants were investigated as electron donors for thermoelectric (TE) carbon nanotubes (CNTs). The oxygen-barrier properties of the surfactant wrapping the NT surface and electron-donating effect of oxyethylene oxygen atoms enabled the preparation of n-type CNTs. The TE output of these NTs was comparable with that of conventionally used dopants.
