Study the thermal stability of functionalized graphene oxide

Graphene oxide (GO) has various functional groups attached on their surface which facilities the attachments of other external group through covalent and non covalent substitution. Because of the advantage of chemical method for bulk production, Hummer’s method was used for the synthesis of graphene oxide from the graphite. Functionalization of Graphene oxide was also done using chemical route. The functionalized GO was characterized using various characterization techniques like, X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA). In XRD the diffraction shifting of diffraction peak confirms the functionalization of the GO with nitro aniline. TGA represents the change in thermal stability of GO after the functionalization. It was observed that the thermal stability of GO was improved by functionalization using Nitro aniline.
