Liquid-phase Exfoliation of Graphite to Produce High-quality Graphene

Graphene has attracted intense interest due to its exceptional physical and chemical properties as well as its wide potential applications. For applications of two-dimensional graphene, commercially viable sources are necessary. Liquid-phase exfoliation graphite is one of the most promising economical mothed for the mass production of graphene. A number of methods have been developed to achieve exfoliation of graphite, each with advantages and disadvantages. Here, we present a brief overview of the main developments in this research area over the last few years. Particularly, we present and discuss the current status of liquid-phase exfoliation of graphene from pristine graphite, highlighting some of the obstacles that have been encountered along the way and the approaches proposed to overcome them.
