Abstract

Purification and functionalization of carbon nanotubes have been examined using different acid treatments. CNTs treatment may vary depending on the desired outcome. The results show that HCl as a strong acid, oxidizes all the materials present in the sample. HNO₃acts as an oxidizing agent which is useful to produce functional CNTs. H₂O₂behaves as a regulator in presence of both acids. The results suggest that H₂O₂may be a critical element to control the outcome of CNTs purification and functionalization process.
