Novel method for graphene synthesis using PVC through electron beam irradiation

Graphene is an ideal two-dimensional material backboned with sp2-hybridized carbon atoms and draws significant interest due to its superior electrical properties represented by its high carrier mobility and its remarkable structure stability. Based on these excellent characteristics, graphene is assessed as a material with unlimited potential for practical uses. Graphene has been evaluated as a next generation material due to its superior electrical properties compared to conventional materials. However, conventional methods to synthesize graphene have many disadvantages in commercialization so a new method is required. We have presented a novel method to synthesize the graphene through electron beam irradiation on PVC film. Raman spectra of PVC film irradiated with electron beam shows that generated material in PVC film by electron beam has the characteristics of graphitic material having defects. Besides, the degree of graphite increases more as the electron beam dose increases. However, much data is required to optimize the experimental condition. To summarize, multi-layer graphene would be synthesized with electron beam as controlling the absorbed dose and more data should be required to optimize the condition of electron beam.
