Graphene oxide and reduced graphene oxide


Graphene oxide is derived by oxidation of graphite. Graphene oxide includes oxygen functional groups such as epoxide, hydroxyl, carboxyl groups. Graphene oxide can bind to other molecules. It is hydrophilic. Because of its properties, graphene oxide reaches a wide range of application fields.


Reduced graphene oxide is derived via reduction of graphene oxide. Reduced graphene oxides have fewer layers then ten shows graphene-like properties. İt is highly hydrophobic.

What is graphene?

Graphene is a nanomaterial with attractive properties such as 2630(m2/g) theoretical specific surface area, 250,000(cm2/Vs) electron mobility, and quantum Hall effect. 5000(W/mK) thermal conductivity, 1TPa elastic modulus, 97,4 % optical transmittance.

Graphene has higher electrical conductivity than copper, 200 times stronger than steel, higher thermal conductivity than carbon nanotubes and diamond, higher specific surface area and optical transmittance.

Graphene has a wide range of applications such as FET (Field Effect Transistors), sensors, transparent electrodes, photodetectors, solar panels, energy storage devices, polymer composites and nanocomposites, hydrogen storage, fuel cells, absorbent, support materials for catalysis, heat transfer material, capacitors and batteries.
