▎ 摘　　要

The transient cavitation of diaromatic components such as 1-methylnaphthalene has been used to produce graphene platelets in a 'bottom-up' synthesis via the high temperature (> 5000 K) conditions that are generated inside collapsing bubbles. Acoustic cavitation produced yields of 5.7 x 10(-11) kgJ(-1) at a production rate of 2.2 x 10(-9) kgs(-1). This can be improved by generating cavitation hydrodynamically, thus making commercial scale production viable. Hydrodynamic cavitation produced platelets with larger lateral dimensions (>= 2 mu m) than those formed by acoustic cavitation (10-200 nm). The partially oxidised nature of the platelets enables their covalent chemical functionalisation, which was achieved by combining suitable molecules in the reaction medium to affect a one-pot formation and functionalisation of graphene.
