The atomic force microscopy (AFM) is a direct and visual analytical method to examine the topographical and cross-sectional features of graphene materials. In this study, AFM was carried out, in parallel to HR-TEM, to determine the number of GO layers. Fig. 4 shows the AFM images of GO sheets exfoliated in different polar solvents. In general.

Previous studies using AFM analysis have shown that the thickness of monolayer graphene nanosheets, and the inter-layer spacing are about 0.57 nm, and 0.6-0.7 nm, respectively.
Graphene Analysis with Atomic Force Microscope (AFM)
Atomic force microscopy (AFM) is utilized in determining the surface structure and thickness of graphene [84]. An AFM generates images by scanning a small cantilever over the surface of a sample. The sharp nanoscale tip at the end of the cantilever contacts the surface, thus bending the cantilever and changes the amount of laser light reflected.
