Fluid dynamics: an emerging route for the scalable production of graphene in the last five years
Bulk applications of graphene in fields such as advanced composites,
conductive ink, and energy storage require cheap and scalable graphene.
Fortunately, in the last decade, liquid-phase exfoliation of graphite to give
pristine graphene has been thought as a promising way to massive production of
graphene at high efficiency and low cost, in terms of the cheap and abundant
graphite source and a variety of cost-effective exfoliation techniques. Though
many exfoliation techniques are available so far, this article will highlight
the recent progress of fluid dynamics route which emerges as a promising
scalable and efficient way for graphene production in the last five years. The
emphasis is set on vortex fluidic devices and pressure- and mixer-driven fluid
dynamics, with our perspectives on the latest progress, exfoliation mechanism,
and some key issues that require further study in order to realize industrial
applications.Comment: 18 figure
