Functionalization of Graphene Nanoplatelets Using Sugar Azide for Graphene/Epoxy Nanocomposites

Abstract

We report a covalent functionalization of graphene nanoparticles (GnPs) employing 2,3,4-Tri-O-acetyl- -D-xylopyranosyl azide followed by fabrication of an epoxy/functionalized graphene nanocomposite and its thermo-mechanical performance evaluation. Successful functionalization of GnP was confirmed via TGA and XPS study. Raman spectroscopy indicated that the functionalization was on the edge of graphene sheets as the basal plane was not perturbed as a result of the functionalization. Epoxy/functionalized GnP composite system produced an increase in the flexural modulus (~18%) and glass transition temperature (~10 deg C) compared to an un-functionalized GnP based epoxy composite.
