Layered materials

Titanium disulfide is an example of a layered material. The individual sheets are interconnected by van der Waals forces between the sulfide centers.

In material science, layered materials are solids with highly anisotropic bonding, in which two-dimensional sheets are internally strongly bonded, but only weakly bonded to adjacent layers.[1] Owing to their distinctive structures, layered materials are often suitable for intercalation reactions.[2][3]

One large family of layered materials are metal dichalcogenides. In such materials, the M-chalcogen bonding is strong and covalent. These materials exhibit anisotropic electronic properties such as thermal and electrical conductivity.
