Graphene is a sheet of Carbon atoms, or one layer of Graphite ("lead" in a pencil). A graphene filter is a filter made of graphene.
Graphene is pretty amazing. An adequate description of the properties is rather long. There is a link below to the properties section of an article on graphene.
Graphene is formed by peeling extremely thin layers of graphite off of a larger piece, in the original paper published on graphene it was done using tape.
Graphene is a very thin layer of graphite. It is so thin, it is so close to being invisible!
One of the hardest substances found in nature is the diamond. One of the strongest man made materials is called graphene.
The molecular structure of graphene differ from the other allotropes of carbon diamond and graphite in that graphene consist of a single layer of atoms.
graphene according to how much it can hold (calculator) and how dense it is.
It would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap."
