What is Graphene?

Graphene is a one atom thick sheet or film of carbon atoms. It is strong yet low weight and it conducts heat and electricity. In fact, graphene is the most thermally conductive material known to man. Scientists had theorized about graphene for decades before it was successfully synthesized in the lab in 2004 by Geim et al. It is two-dimensional, it interacts favorably with light and with other materials.  Graphene is a highly crystalline carbon sheet. Carbon atoms are densely packed in a regular hexagonal sp2 bonded structure. It can best be envisioned as a one-atom thick layer of graphite.

Graphene Products

We specialize in providing a wide variety of high quality, low cost graphene products.  We supply modified hummers method Graphene Oxide-GO in both Single and Few Layer Layer form.  We supply our high quality Graphene Nanoplatelets-GNPs in pristine or functionalized versions. Monolayer CVD graphene films as well as spin coated GO films which are available in oxide or reduced forms. Please contact us today to discuss your needs.

Our Grade 4 Graphene Nanoplatelets-GNPs are exfoliated from crystalline graphite. We use Sri Lankan vein graphite, the most crystalline graphite available.  They can be functionalized with a wide variety of groups and we can tailor the amount to your application. They are friable so the layers separate (disperse) easily from each other.  GraphenX is fully synthetic and made from CO2 and MgO, it isn't mined so it doesn't have the same variations as raw graphite has.

Cheap Tubes can also supply single layer and few layer graphene oxide dispersions. Our standard concentration is 2mg/ml but higher concentrations up to 10mgs/ml are available.  Please inquire with us to find out pricing.  We can provide our graphene oxide dispersions in Water or DMF solvents without the use of surfactants. We also supply dispersed graphene nanoplatelets which do require stabilization with surfactants.
