MAX exfoliation: Surprisingly simple method to make 2D graphenelike carbides

Graphene, a two-dimensional sheet of carbon, has been the subject of much research since it was discovered in 2004. Graphene is interesting, but its range of properties is limited by its supersimple chemistry. In multilayer form, weak van der Waals bonding between layers is a limiting factor, too. I...

Summary:Graphene, a two-dimensional sheet of carbon, has been the subject of much research since it was discovered in 2004. Graphene is interesting, but its range of properties is limited by its supersimple chemistry. In multilayer form, weak van der Waals bonding between layers is a limiting factor, too. If 2D materials with more complex chemistries could be made, the door would be opened to tune properties and engineer materials for specific applications. Drexel University professors Yury Gogotsi and Michel Barsoum have found a process for synthesizing 2D carbides, which they describe in a new paper, "Two-Dimensional Nanocrystals Produced by Exfoliation of Ti3AlC2," in Advanced Materials.
