CONTRERAS-NAVARRETE, J. J. et al. MWCNTs oxidation by thermal treatment with air conditions. Superf. vacío [online]. 2015, vol.28, n.4, pp.111-114. ISSN 1665-3521.

A functionalization process has to occur in order to employ carbon nanotubes, generally by using certain types of acids. Multiwalled carbon nanotubes synthetized from benzene and ferrocene were oxidized at different temperatures between 270-600 °C through thermal treatment at atmospheric conditions. Samples were characterized by SEM, EDS, XRD, FTIR and Raman. The weight loss is shown with fluctuations from 0-78% according to different temperature conditions. FTIR analysis demonstrated presence of carbonyl groups and decrease of CHx.

Palavras-chave : carbon nanotubes; oxidation; carbonyl group.
