Our graphene oxide is noted for its mechanical and thermal properties. The raw material - graphite - is chemically processed to obtain monolayer flakes of graphene oxide.
Properties
- · Form: Dispersion of graphene oxide sheets
- · Particle Size:
- - D90 5-7 μm
- - D50 2-4 μm
- - D10 1-2 μm
- · Color: Yellow-brown
- · Odor: Odorless
- · Dispersibility: Polar solvents
- · Solvent: Water
- · pH: 2,2 - 2,5
- · Concentration: 0.4 wt%
- · Monolayer content (measured in 0.05 wt%): >95% (*)
- · The Graphene Oxide weight content is guaranteed
- · The dispersion volume is approximated
(*) 0.4% wt% concentration tends to agglomerate the GO flakes and dilution followed by slight sonication is required in order to obtain a higher percentage of monolayer flakes.
Elemental Analysis
- · Carbon: 49 – 56%
