Graphene is a promising material for replacing indium tin oxide (ITO) in transparent conductive flat panels. Currently, ITO is widely used as the transparent electrode in flat panel displays. However, indium is expensive and has a limited reserve in nature. In addition, ITO is not appropriate for flexible display devices due to limitations in its mechanical and optical properties. Recently, many researcher made an effort through various approach such as Chemical vapor deposition(CVD) and reduced graphene oxide(rGO) to replace ITO. However both approaches have some problem. CVD methods need high cost and process of CVD is not easy. Graphene film from the rGO system has poor quality because of limitation of reducing conversion. Here, we report the formation of large area, flexible, conductive, and transparen graphene films via a simple solution casting of exfoliated platelets from edge-selectively functionalized graphite (EFG) using“direct” Friedel Crafts acylation in PPA/P2O5. |
