Figure 1: Characterization of Graphene Oxide (GO) sheets.
From: Graphene Oxide Demonstrates Experimental Confirmation of Abraham Pressure on Solid Surface

(a) SEM image shows the exfoliated GO sheet. (b) TEM image of GO sheet; Inset in Fig. 1b shows the SAED pattern of GO. (c) Raman spectra of GO showing D, G and 2D band. (d) FTIR spectra of GO showing the presence of different functional groups.
