石墨烯在先进复合材料、导电油墨和储能等领域的大量应用需要廉价且可扩展的石墨烯。幸运的是，在过去的十年中，石墨的液相剥离以获得原始石墨烯已经成为一种有前途的方式，通过利用廉价且丰富的石墨源和各种具有成本效益的剥离技术，以高效率和低成本实现石墨烯的大规模生产。虽然有许多剥离技术可用，但本文将重点介绍流体动力学路线的最新进展，该路线在过去五年中已成为一种有前途的可扩展和有效的石墨烯生产方法。重点介绍了涡流射流装置、压力驱动流体动力学和混合器驱动流体动力学，并对最新进展、剥离机理以及实现工业应用需要进一步研究的关键问题进行了展望。
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, the liquid-phase exfoliation of graphite to obtain pristine graphene has emerged as a promising way to achieve massive production of graphene at high efficiency and low cost by utilizing a cheap and abundant graphite source and a variety of cost-effective exfoliation techniques. Though numerous exfoliation techniques are available, this article will highlight the recent progress in the fluid dynamics route, which has emerged in the last five years as a promising scalable and efficient method for graphene production. A focus is made on vortex fluidic devices and pressure- and mixer-driven fluid dynamics, with our perspectives on the latest progress, the exfoliation mechanisms, and some key issues that require further study in order to realize industrial applications.
