1 Introduction. With hundreds of discovered members, and thousands more predicted, the big family of 2D materials exhibits an immense range of physical and chemical properties. [] Most of these materials can be either synthesized by a solution-based method or exfoliated from a layered crystal in a liquid. [] In either case, the final product is a suspension …
