This study examines the influence of different sizes of graphene oxide flakes on their chemical composition and intrinsic properties. The results show that there are slight variations in the composition of chemical moieties and slight fluctuations in the edge-to-basal plane ratio and carbon-to-oxygen ratio as the flake size increases.
The size of graphene oxide (GO) flakes may change the chemical composition on the surface, thereby altering its intrinsic properties. The current work explored the variations of surface moieties with four different sizes: 0.3, 0.7, 20, and 42 mu m(2), which were obtained with morphological integrity under controlled fabrication technique. On the basis of comprehensive analyses, slight variations in the composition of each chemical moiety were observed. At the same time, slight fluctuations were found for both edge-to-basal plane (E/B) and carbon-to-oxygen (C/O) ratios with increasing flake size.
