Graphene: Graphite-to-Graphene: Total Conversion (Adv. Mater. 8/2017) Academic Article uri icon


  • The addition of a protective diluent (e.g., pyrene) to graphite during ball-milling results in a game-changer yield (>90%) of defect-free graphene, as described in article number 1603528 by Matat Buzaglo, Oren Regev, and co-workers. In the non-protected milling, there is a continuous fragmentation leading to amorphous carbon formation, whereas in a diluent-protected milling, the diluent adsorbs part of the impact forces, enabling exfoliation into graphene, whose size is controlled by the milling energy and the diluent type.
