Graphene oxide powder2D Material for Processing at High Concentrations
High quality and high purity (99.5%) single layer graphene oxide
Overview | Product Information | Related Products
Graphene oxide (CAS number 1034343-98-0) is one of the most popular 2D materials available. This is due to the wide range of fields that it can be applied to. It has a distinct advantage over other 2D materials (such as graphene), as it is easily dispersed within solution; allowing for processing at high concentrations. This has opened it up for use in applications such as optical coatings, transparent conductors, thin-film batteries, chemical resistant coatings, water purification, and many more.
Ossila have two types of graphene oxide powders available, with flake sizes between 1 - 5 µm.

Dispersion Guide
Due to the presence of oxygen and hydroxide groups, the dispersibility of this material is significantly better than other 2D materials (such as graphene). High concentrations of GO can be dispersed in polar solvents, such as water. At Ossila, we have found that the most stable solutions can be produced using the following recipe:
- Weigh out desired amount of material, this can go up to at least 5 mg.ml-1.
- Add 1:1 ratio of deionized water to isopropyl alcohol.
- Shake vigorously to break up material.
- A short treatment in an ultrasonic bath will rapidly disperse the material.
- For larger flakes, use a mechanical agitator instead (as sonication may damage the flakes).
