A process comprises combining a Ce (IV) salt with a carbon material comprising CNT or graphene wherein the Ce (IV) salt is selected from a Ce (IV) ammonium salt of a nitrogen oxide acid and is dissolved in a solvent comprising water. The process is conducted under conditions to substantially oxidize the carbon material to produce an oxidized material that is substantially non-conducting. After the oxidation, the Ce (IV) is substantially removed from the oxidized material. This produces a product made by the process. An article of manufacture comprises the product on a substrate. The oxidized material can be formed as a pattern on the substrate. In another embodiment the substrate comprises an electronic device with the oxidized material patterning non-conductive areas separate from conductive areas of the non-oxidized carbon material, where the conductive areas are operatively associated with the device. |
