Efficient and scalable production of two-dimensional (2D) materials is required to overcome technological hurdles towards the creation of a 2D-material-based industry. Here, we present a novel approach developed for the exfoliation of layered crystals, i.e., graphite, hexagonal-boron nitride and transition metal dichalcogenides. The process is based on high-pressure wet-jet-milling (WJM), resulting in a 2 L h⁻¹ production of 10 g L⁻¹ of single- and few-layer 2D crystal flakes in dispersion making the scaling-up more affordable. The WJM process enables the production of defect-free and high quality 2D-crystal dispersions on a large scale, opening the way for their full exploitation in different commercial applications, e.g., as anode active material in lithium ion batteries, as reinforcement in polymer–graphene composites, and as conductive inks, as we demonstrate in this report.

通过湿式喷射铣削可高产量地生产2D晶体†

需要有效且可扩展的二维（2D）材料生产，以克服创建基于2D材料的行业的技术障碍。在这里，我们提出了一种用于剥落层状晶​​体（即石墨，六方氮化硼和过渡金属二卤化物）的新方法。该工艺基于高压湿喷射研磨（WJM），可在分散状态下以10 g L ^-1的单层和多层2D晶体薄片的2 L h ^-1产量生产2L h ^-1负担得起的。该WJM方法能够生产大规模无缺陷和高品质的2D-晶体分散体，它们在不同的商业应用充分利用，开辟了道路例如正如我们在本报告中所展示的，它是锂离子电池的负极活性材料，聚合物-石墨烯复合材料的增强材料以及导电油墨。
