Graphite was chemically cleaved to graphene by Billups Reaction, and the morphologies and microstructures of graphene were characterized by SEM, Raman and AFM. The results show that the graphite was first functionalized by 1-iodododecane, which led to the cleavage of the graphene layer in the graphite. The second decoration cleaved the graphite further and graphene was obtained. The heights of the graphene layer were larger than 1 nm due to the organic decoration.
