Noncovalent Functionalization of Graphene in Suspension
Figure 2
(a) Overview TEM of as-prepared graphene dip-deposited from toluene, the arrow pointing to a flake edge suspended over a hole in the grid, a suitable point of analysis by HR-TEM, and (b) Raman spectrum (514 nm) of drop-deposited graphene flakes from the same preparation. Both analyses prove the presence of few-layer graphene.
