Summary:

Current work presents novel method for mass production of bulk graphene in a plasma-based process. Application of plasmas is a well-known tool widely utilized in nanomanufacturing due to significant enhancement of the reactivity of species involved in synthesis by means of plasmas causing improvement of final properties of the synthesized nanostructures. The method utilizes arc discharge supporting by ablation of pure carbon electrode. Conditions of synthesis such as arc current, background gas type and pressure, substrate temperature, material and exposure time were optimized. The synthesis method yields graphene production rates of about few hundred milligrams per second.
