Graphene Materials

About

Graphene has been in the research spotlight since its discovery in 2004. It has excellent mechanical, electrical, chemical, optical, and thermal properties with great specific surface area. Like diamond, graphene is pure carbon. It is defined as a two-dimensional single layer of carbon atoms bonded together in a hexagonal honeycomb lattice structure. Each carbon atom is bonded to three adjacent carbon atoms through a σ bond. Graphene is flexible, strong, and lightweight. With a sheet thickness of 0.34 nm, it is the thinnest and strongest nanomaterial, estimated to be 200 times stronger than steel. Graphene oxide (GO) involves rich active oxygen-containing functional groups, such as epoxide, carbonyl, carboxyl, and hydroxyl groups. Reduced graphene oxide (rGO) contains residual oxygen and other heteroatoms, as well as structural defects. We have a great collection of graphene materials including graphene oxide, graphite, doped graphene powder, graphene carbon nanotubes composites, and graphene sheets and films.

Graphene vs Graphite Graphene is a single layer of carbon atoms arranged in a hexagonal pattern, like a sheet of paper. Graphite, on the other hand, is made up of many layers of graphene stacked on top of each other, like a stack of paper. Read more...
