Outline of Final Research Achievements

In this study, we investigated synthesis of large graphene grain by atmospheric and low pressure CVD method using waste plastics and polystyrene as precursor. An oxide layer on copper foil was prepared by annealing treatment to achieve large graphene domain growth. The graphene nucleation was controlled by argon and hydrogen annealing process, and synthesis of large graphene grain was achieved by the CVD method. We were able to growth graphene domain as large as 1.6 mm using waste plastic as precursor. Furthermore, transparent electrode was prepared using the synthesized graphene film form waste materials. A sheet resistance of 120 Ω / Sq was achieved with a transmittance of 90% using the synthesized graphene film.
