Ball milling is a widely used method to produce graphene and other twodimensional (2D) materials for both industry and research. Conventional ball milling generates strong impact forces, producing small and thick nanosheets that limit their applications. In this study, a viscous solventassisted planetary ball milling method has been developed to produce large thin 2D nanosheets. The viscous ...
