Graphene Oxide Water Dispersion (0.4 wt% Concentration)

Graphene Oxide

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: < 10μm
  • · 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%
  • · Hydrogen: 1 – 2%
  • · Nitrogen: 0 – 1%
  • · Sulfur: 2 – 4%
  • · Oxygen: 41 – 50%

Quality control

Our Graphene Oxide is subjected to a rigorous QC in order to ensure a high quality and reproducibility.

  • · Amount of residue on evaporation
  • · pH control
  • · Elemental Analysis
