A highly efficient and easily transferable poly(vinyl alcohol) (PVA)-assisted exfoliation method has been reported, allowing for the large-scale production of van der Waals materials. This approach overcomes the preparation bottleneck for the large-scale applications of two-dimensional (2D) materials.
We report a highly efficient and easily transferable poly(vinyl alcohol) (PVA)-assisted exfoliation method, which allows one to obtain van der Waals materials on large scales, e.g., centimeter-scale graphite flakes and hundred-micrometer-scale several layers of ZnIn2S4 and BN. The present exfoliation scheme is nondestructive, and the materials prepared by PVA-assisted exfoliation can be directly fabricated into devices. This exfoliation approach could be helpful in overcoming the preparation bottleneck for large-scale applications of two-dimensional (2D) materials.
