Graphene is a two-dimensional one-atom-thick carbon nanomaterial that has drawn significant attention since the first discovery in 2004. Owing to its unique and superior electrical and optical properties, graphene is regarded as one of the most promising candidates as transparent electrodes for displays, solar cells, and touch sensors. The most commonly used process for graphene solutions is a chemical exfoliation method through chemical oxidation and reduction, known as Hummer’s method. Despite the reduction treatments, oxygen functional groups remain in the reduced graphene oxides, which lead to lower conductivity compared to pristine graphene. In this work, we employ non-oxidation intercalation method to achieve high-quality graphene flakes from graphite and demonstrate highly conductive, transparent graphene films by chemical doping of the obtained graphene. |
