| Outline of Final Research Achievements |
We constructed the liquid-phase vacuum ultraviolet (VUV) light irradiation processes for photochemical surface treatments by utilizing an ultra-thin liquid film, which can be penetrated by the VUV light. The graphene oxide (GO) sheets on the substrate were irradiated by VUV light through 100 nm liquid film of an organic solvent. We concluded that this photo-irradiation process can be effective for reduction of GO sheets. Furthermore, an alkylamine additive in the liquid film can react with the GO sheet through this process.
