Graphene oxide nanoplatelets: The role of hydroxyl and epoxy bridges in basic physical properties and global reactivity

Basic physical properties and global reactivity in graphene oxide (GO) nanoplatelets, were studied experimentally by different physical characterization techniques, as presented here. GO structures with hydroxyl and epoxy bridges were proposed and the first principles calculations were performed, via density functional theory (DFT) in GO structures; obtaining, a high concordance between theory and experiments. These results suggest a basic description of the GO physics and potential technological applications of GO in advanced electronics of sensors and devices.
