Creating Low-Cost, Defect-Free Graphene

Sep-02-16 A team of French chemists has found a way to produce defect-free graphene at a low cost.

Graphene is being used in a huge array of new technologies, and so the demand for affordable, defect-free versions is on the rise. To address the challenge, the team from Friedrich-Alexander-Universiät Erlangen-Nürnberg (FAU) found a way to produce the graphene directly from a solution. The key to the new technique is the solvent benzonitrile, which allows the graphene to be removed from the solvent without any additional functional groups forming in the process.

According to Dr. Andreas Hirsch, team leader, the discovery could lead to “major advancements in terms of the applications of this type of graphene which is produced using wet chemical exfoliation. An example could be cutting defect-free graphene for semi-conductor or sensor technology.”
