Graphene as a manufactured product : a look forward

Abstract

Graphene's unique electrical and mechanical properties have brought it into the spotlight in recent years. With the number of patents increasing rapidly every year, production of the material is becoming more and more important We evaluate various production methods of Graphene, including Chemical Vapor Deposition, Exfoliation, SiC synthesis, and Nanotube Unzipping. Key findings report CVD having the largest potential for large-scale production for most applications with lower quality requirements, while exfoliation of graphite produces lower quality graphene for applications that do not need large sheets of graphene. Currently, CVD has been able to produce sheets of graphene with diagonal sizes of 40", with high transparency. Using the roll-to-roll method, these sheets have proven viable on flexible touchscreen devices.
