Graphene
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 products including graphene oxide, graphite, doped graphene powder, graphene carbon nanotubes composites and graphene sheet and films.
