Высокое качество однослойный Графен на медной фольги

One 3"x3" sheet

We offer graphene films that are predominantly single-layer graphene. These graphene films are grown on copper foil and continuous across copper surface steps and grain boundaries. Graphene is grown on both sides of the copper foil. If you require specifically graphene on one side only, please contact us directly.
Etching of the underlying copper foil allows the carbon films to be transferred to other substrates such as glass, silicon dioxide or plastic films.

To the best of our knowledge, there is no report about degradation of the CVD graphene over time when it is kept in a safe,dry place. The copper foil with single-layer graphene can exhibit some coloration due to slow oxidation of the copper foil,which does not affect the quality of the graphene film.
