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 epoxyfunctionalized 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. Epoxyfunctionalized 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.
