Industrial scale production of layer materials via intermediate-assisted grinding

Scientists from Tsinghua University report an interMediary-Assisted Grinding Exfoliation (iMAEG) technology to massively exfoliate various layer materials into 2D materials. Taking h-BN as an example, ultrathin h-BN nanosheets with an average lateral size of 1.2 μm are obtained. Besides, the production rate (0.3 g h-1) and energy consumption (3.01×106 J g-1) are one to two orders of magnitude better than previous results, showing its huge potential for commercial scale production of 2D materials.
