General description

Each graphene unit sold is accompanied by a specification sheet unique to the S/N and contains batch-specific metrics. This eliminates guesswork and ensures that you only get the best, well-characterized, and QA-passed graphene.


Graphene is one of the most promising carbon nanomaterials, and it was first isolated in 2004 by Novoselov, Geim et al, leading to a Nobel prize. It consists of a two-dimensional single layer of sp2 hybridized carbon with hexagonal lattice. It has attracted significant attention in the field of high-performance electronic devices because of its excellent electronic and chemical properties, and large specific surface area . Among the main potential applications of our monolayer graphene on Si/SiO2 wafers are transistors and sensors.

Storage and Stability

To ensure the maximum shelf life of your graphene sample, especially if it rests on copper foil, it is best stored under vacuum or in inert atmosphere (Argon or Nitrogen) conditions once the vacuum sealed package has been opened.

Storage Class

13 - Non Combustible Solids
