It’s all in how you make it.
Graphene is a highly prized material due to its ultra-strong, flexible and lightweight qualities, but producing it at large scale has been a challenge.
A team of researchers led by the National University of Singapore (NUS) claims to have come up with a way to more efficiently produce graphene, thus making our graphene future ever more attainable. Traditionally, graphene is harvested from graphite (yes, the same stuff in your pencil) using sound energy or shearing forces. The graphene is then thrown into an organic solvent to disperse the layers. Simple enough, right?
Wrong. See, graphene tends to reform back into graphite once in the solvent. According to The Engineer, current production requires at least one tonne of solvent to yield one kilogram of graphene. Not exactly cost effective for businesses or good for the environment.
