Graphene Oxide

JMC has over 65 years of know-how and experience producing the highest quality materials and delivering reliable supply to customers around the world. The materials that JMC produces now include graphene-based materials. JMC also leverages the expertise and networks of the KISCO group which has deep experience supplying materials for electronics into the Korean and other international supply chains.

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. Graphene oxide can though, be used directly in a range of applications where it can impart improved strength, thermal and electrical conductivity to composite materials.

JMC’s scalable Graphene Oxide production process can control the lateral size of graphene oxide particles from 10 to 40 micrometres while still achieving specifications of over 80% 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 2% 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.
