The effects of acid treatment on the thermoelectric power of multiwalled carbon nanotubes synthesized by chemical vapor deposition

- Seebeck coefficient of acid treated multiwalled carbon nanotubes was measured.
- Seebeck coefficient of acid treated MWNTs is effected by oxygen rich reagents.
- Nitric and sulfuric acids lead to a 8-15% increase in the Seebeck coefficient of MWNTs.
- Increasing the molarity and reflux time enhances the improvement to the Seebeck coefficient.
