Graphene price – the different types of products available on the market and their average costs

Listed below are some graphene products and graphene prices that are now available for purchase:

Graphene Oxide Gel: $125 – $175 / gram

Graphene oxide gel contains graphene oxide, which is an oxidized form of graphene. Because it is dispersible in solvents like water and ethanol, this makes it easy to process and even reduced to graphene if needed. Due to the many voids in its structure caused by the oxidation process, graphene oxide gel does not make a very good conductor. However, this is reversible so if it is reduced, then the structure can easily be restored, now making it a good conductor.

Reduced Graphene Oxide: $400 – $450 / gram

Reduced graphene oxide is available in many forms, including powder form, dispersed or as a coating on substrates. Research into making derivatives or related materials that is both inexpensive yet effective has been of extreme interest. Graphene oxide is an oxidized form of graphene imbedded with oxygen-containing groups. When graphene oxide is reduced, these functional groups are removed in order to restore the original carbon structure of the compound in order to take advantage of graphene’s unique properties. Unlike graphene oxide which is insulating, reduced graphene oxide is a conductive compound but is difficult to produce.

Single Layer Graphene Oxide (1-20um): $400 – $450 /gram

Single layer graphene oxide (SLGO)is supplied by the milligram, gram, Kg in power form, dispersed or as a coating on substrates. SLGO is madeby reacting graphite with a strong oxidizing agent in order to promote atomic layer separation, and to introduce significant functional groups onto the compounds surface area. This surface functionalization of oxygenated groups in significant quantities can make the material hydrophilic so that it doesn’t need surfactants when dispersed in water or other solvents like Di Water, NMP, DMF and DCP.

Monolayer Graphene Film-PET (10mm x 10mm): $229 / 4-pack

The monolayer graphene film-PET is grown on piece of copper foil that is 50 microns thick and coated with a single layer of graphene which is deposited using the chemical vapor deposition method. Products on the PET (polyethylene terephthalate polymer) substrate are transferred there using a wet transfer process. This product is flexible so it can be used for flexible electronics, and other applications in microelectronics, micro- and nano- electrochemical systems, field effect transistors and chemical/biological sensors.

Graphene price – the price of GNPs

Graphene Nanoplatelets: $0.45 – $15.00 / gram

Graphene nanoplatelets, or GNPs, are small layers of graphene that are able to replace other carbon structures like carbon fiber, carbon nanotubes, nano-clays and other compounds that have composite applications. Even with just the addition of trace amounts (1-5wt%) of graphene nanoplatelets to plastics or resins, the chemical and physical propertiesare significantly altered. The materials are now electrically or thermally conductive, less permeable to gas and have improved mechanical strength, stiffness, permeability or surface roughness.

  • Graphene Nanoplatelets Non Functionalized: $2.50 – $40.00 / gram
  • N2 Functionalized Graphene Nanoplatelets: $2.50 – $40.00 / gram

Introducing N2 onto the surface of GNPs promotes faradaic pseudocapacitive reactions. Capacitive behavior is enhanced by pyridinic and pyrrolic functional groups, while electron transfer is improved due to quaternary nitrogen and pyridinic-N-oxide.

  • Si Decorated Graphene Nanoplatelets:$2.50 – $40.00 / gram
  • F Functionalized Graphene Nanoplatelets: $2.50 – $40.00 / gram

Fluorine is used to produce C-N bond formation, free radical addition and cycloaddition

  • NH2 Functionalized Graphene Nanoplatelets – $2.50 – $40.00 / gram

Further chemistry of the functionalized carbon nanotubes occurs due to the amino termination. This makes covalent bonding to polymers and biological systems, like DNA and carbohydrates, possible.

  • COOH Functionalized Graphene Nanoplatelets -2.50 – $40.00 / gram

COOH introduction can be handy when working with paints, polymers, epoxies and inks.

  • O+ Functionalized Graphene Nanoplatelets – 2.50 – $40.00 / gram

Oxygen groups promote dispersion in aqueous solutions, but does not necessarily entail that the compound is water soluble. In order to stabilize dispersion in DI water (or other aqueous solvent mixtures), surfactants may be required.
