Liquid- phase exfoliation (LPE) is the principal method of producing two-dimensional (2D) materials such as graphene in large quantities with a good balance between quality and cost now widely adopted by both academic industrial sectors. The fragmentation mechanisms involved have usually been simply attributed to force induced ultrasound interaction solvent molecules. Nonetheless, little known about how they actually occur, i.e., thick graphite crystals can be exfoliated into thin small...
