Graphene stays at the heart of material science research due to its unmatched combination of remarkable properties: exceptionally high electrical conductivity, remarkable mechanical strength, and very good thermal conductivity. In the last two decades, important progress has been made both in the understanding of its atomic structure and in synthesizing high-quality graphene at an industrially relevant scale. Of these, techniques such as CVD and electrochemical exfoliation are among the most promising, yet considerable barriers to manufacturing in a cost-effective, defect-free manner remain. The versatility of graphene, nonetheless, allows for numerous applications: in electronics, energy storage, and composite materials.
