Graphene Oxide

Graphene-based materials continue to attract significant interest for use in a large variety of products ranging from microelectronics through to large scale applications such as cement and other composites. The properties of graphene-based materials are strongly influenced by the chemical purity of the materials as well as their physical properties.

Graphene oxide is typically soluble and more easily processed than pure graphene. In surface applications, graphene oxide can be deposited onto a substrate and then reduced to graphene. This method has been applied to products such as transparent electrodes and filters.

JMC’s scalable Graphene production process can control the lateral size of graphene particles from 2 to 10 micrometres while still achieving specifications of over 90% of the material being a single layer.


Reduced Graphene Oxide

Graphene Oxide can be reduced to give reduced Graphene Oxide (rGO), a form of Graphene. Graphene is extremely strong and highly conductive, both electrically and thermally. JMC’s rGO has an oxygen content below 1% and can also be made with large laterally-sized particles.

Functionalized Graphene Oxide

Graphene oxide is highly dispersable in water and alcohols due to its hydrophilic functional groups (-OH, -COOH). In order to develop a wide range of graphene oxide composites, high dispersability in organic solvents and polymer resins is desirable. By functionalizing graphene oxide with hydrophobic amine (-NH2) groups, the dispersability of graphene oxide can be improved. In addition, the use of hydrophobic functional groups can enable the formation of hydrophobic surfaces.
