PURPOSE: Micro-patterning of graphene using inkjet printing and applying the micro-patterns to a flexible thin film electrode are provided to freely form patterns have no limit to a form.;CONSTITUTION: A method for forming a flexible graphene thin film electrode is as follows. A water-dispersible graphene oxide nanoparticle solution utilized as conductive ink for an inkjet printing is manufactured after dissolving oxidation graphite in the water by using an ultrasonic generator. Chemical properties of the surface of a polymer film are modulated by plasma-processing so that the water-dispersible graphene oxide nanoparticle solution forms precise patterns on the flexible polymer film. After manufacturing ink by adding an auxiliary solvent into the water-dispersible graphene oxide nanoparticle solution, the manufactured ink is injected into a printer head and discharged by an inkjet printer on the plasma-processed polymer film so that a graphene thin film is formed. The polymer film in which the graphene thin film is formed is arranged inside a vapor deposition reactor. A reduction reaction is processed on the surface of the polymer film by vaporizing a reducing agent for proper time under a proper temperature so that graphene sheet patterns are formed. The graphene sheet variously patterned on the polymer film is utilized as an electrode so that properties of the electrode such surface resistance and flexibility are analyzed.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Water-dispersible graphene oxide nanoparticle solution; (BB) Nozzle; (CC) Plastic substrate; (DD) Front unit; (EE) Rear unit; (FF) Progressive direction; (GG) 27V DC
