A lint roller for superclean graphene

Researchers demonstrate that the amorphous carbon contaminants on CVD-produced graphene, which could greatly degrade its properties, can be removed by an activated carbon-coated lint roller, relying on the strong interactions between the amorphous carbon and activated carbon. Large-area graphene surfaces treated with this lint roller exhibit a high cleanliness of 99% with a low degree of polymer residue after transfer onto a functional substrate. This superclean graphene has extremely low contact resistance and ultrahigh carrier mobility.

Inspired by nacre, epoxy-graphene layered nanocomposites are tough and self-monitoring

To make epoxy-graphene nanocomposites, the graphene nanosheets are commonly mixed homogeneously with the epoxy matrix. However, one of the problems that bedevils these nanocomposites is the issue of agglomeration of the nanofillers. Researchers now report that they have sucessfully tackled this dispersion problem by constructing a continuous graphene-based scaffold. The results show that the team’s novel strategy boosts the fracture toughness to about 3.6 times that of pure epoxy.

Graphene is actually a 3D material as well as a 2D material

Researchers found that 2D graphene has many of the same mechanical properties as 3D graphite, which is a naturally occurring form of carbon made up from a very weak stack of many layers of graphene.
