Outline of Final Research Achievements

In this work, we sought to develop highly stable n-type single-walled carbon nanotubes and an improvement in their thermoelectric properties. We utilized various non-covalent interactions for this purpose. Particularly, considering the appropriate interaction of charged carbon nanotubes with counter ions, we achieved n-type carbon nanotubes stable at a commercial-level. Additionally, this idea was expanded to various doping systems; the encapsulation of dopants inside nanotubes resulted in the production of n-type composites showing unique temperature dependence. Organic colloids with pai-conjugated structures were introduced to nanotube composites, which enabled the preparation of highly-stable all-organic n-type conductors.
