WebThe IR laser irradiation of graphene oxide in vacuum reduces the oxygen content at low and high fluences. The IR laser irradiation of GO in air enhances the oxygen content at fluences lower than 400 mJ/cm(2): at these fluences thermal oxidation processes are present. At higher fluences, instead, the laser treatment reduces the oxygen amount due ... WebGraphene oxide (GO) is an important precursor of graphene. Unlike graphene, GO can be dissolved and dispersed in water or in organic solvent. GO is rich with oxygen functional group such as hydroxyl and epoxy group making it high affinity with water and easy to modify its functionality and processing and far less expensive compare to graphene [1].
