Graphene oxide (GO) has recently attracted the attention of the scientific community due to its unique chemical and physical properties. In this work, nanosheets and nanoribbons of GO were prepared by means of a chemical oxidation treatment, using graphite flakes and multiple wall carbon nanotubes (MWCNT) as precursor agents to obtain
GO. The structural, optical, morphological and thermal properties of nanosheets and nanoribbons were characterized by means of infrared spectroscopy (FTIR), visible ultraviolet (UV-vis) X-ray photoelectrons (XPS), scanning electron
microscopy (SEM) and thermogravimetric analysis (TGA). SEM micrographs show the characteristic morphology of
nanosheets and nanoribbons obtained from graphite flakes and MWCNT, respectively. While the results of FTIR, UV-vis,
TGA and XPS confirmed the existence of numerous oxygen-based functional groups (hydroxyl, epoxy, carbonyl and
carboxyl) in the nanosheets and nanoribbons of GO. These results indicate that the nanosheets and nanoribbons could be used as a very promising material for obtaining composite materials due to the numerous functional groups.
