Surface treatment of cleaved graphene surfaces with UV/ ozone exposure, O2 reactive ion etching, and Ar ion milling was studied by contact angle measurements and atomic force microscopy (AFM). The cleaved graphene surfaces were superhydrophilized to reveal a static contact angle of <5° for water by the physical bombardment and chemical oxidation of oxygenreactive ions in the plasma phase. The surface oxidization enabled the visualization of isolated atactic poly(methyl methacrylate) chains that were spin-cast onto the hydrophilic graphene surfaces by AFM.
