SEM and TEM Analyses of Graphene Oxide Syntheses Obtained with a New Approach

Abstract

Graphene oxide syntheses obtained by bringing a new approach to Hummers method, scanning and transmission electron microscopy analyzes were examined and it was examined whether they fit other graphene oxide syntheses in the literature. From SEM analysis; , it was observed that oxygen-containing functional groups covalently bond with carbon atoms in the basal plane of graphite and deconstruct the sp2 conjugate system, so the morphology of a nano-surface with wavy, folded regions, thin and flexible layers prevails, and the inter-layer gaps are wider than in graphite.. From TEM analysis; it was observed that it exhibits an ultra-thin silky appearance and its edges have a folded veil-shaped morphology, dark and translucent areas appear under the electron beam. It has been determined that these results were compatible with the graphene oxide syntheses in the literature.
