2D nanomaterials – beyond graphene
Two-dimensional (2D) nanocrystals are now recognised as a new form of matter with unusual physical properties and a number of potential exciting applications. Recent developments in the field of two-dimensional nanocrystals such as the chemical modification of graphene and the isolation of monolayers of molybdenum disulfide and boron nitride are reviewed. The different techniques that have been employed to prepare the materials such as mechanical and solution exfoliation, and chemical vapour deposition are discussed briefly. The techniques employed to characterise these 2D materials are described and their properties discussed. Potential engineering applications of 2D materials in fields such as nanocomposites and catalysis are then described.
