Simultaneous Transfer and Doping of CVD-Grown Graphene by Fluoropolymer for Transparent Conductive Films on Plastic

This study investigates the use of chemical vapor deposition (CVD)-grown graphene as a transparent conductive film on plastic substrates, addressing the challenges of polymer residues during the transfer process. The objective is to enhance the electrical and optical properties of the graphene films, which are sought for commercialization as transparent conductive electrodes. We employ a method of simultaneous transfer and doping using fluoropolymer to achieve improved performance while mitigating the adverse effects of residual polymers. The results demonstrate that the treated films exhibit a high DC to optical conductivity ratio comparable to commercial indium tin oxide electrodes, highlighting the effectiveness of our approach. Furthermore, the significance of the findings lies in the potential application of these novel films in flexible electronic devices, paving the way for advancements in transparent conductive materials. The study contributes to the broader understanding of graphene's capabilities and highlights the importance of suitable processing techniques in optimizing its performance for commercial use.
