Polymer “Tape”‐Assisted Ball‐Milling Method Fabrication
2020-7-24 Although the ball-milling method has been widely used to exfoliate the bulk layered materials into 2D materials, it is rarely used to prepare air-sensitive species, such as black phosphorous and Bi. The high energy and large force would lead to the oxidation of the as-prepared nanomaterials even with a trace amount of oxygen inside.
