MWCNTs oxidation by thermal treatment with air conditions

A process of functionalization, generally using acids, has to occur in order to use carbon nanotubes for different applications. The aim of this research was the oxidation of MWCNTs at air presence with thermal treatment. MWCNTs were obtained using benzene and ferrocene. The MWCNTs were heated into an electric furnace. Temperature ranged between 270 – 600 °C. The samples were characterized by SEM, EDS, XRD, FTIR and Raman. The results shown lost in weight percentage that fluctuated from 0 to 78% according to different temperature conditions. FTIR analysis demonstrated presence of carbonyl groups and decrease of CHx.
