Available Options

    • Available solvents
    • · Water
    • · Acetone
    • · DMF
    • · DMSO
    • · Ethanol
    • · Methanol
    • · NMP
    • · tetra-Butyl acetate
    • · Your solvent
    • Available concentrations
    • · Up to 2.5 wt% (concentration may be limited due to solvent choice)

 

  • * Pricing above is based on a concentration of 0.1 wt%
       
    * Additional charges may apply based on desired concentration, solvent and/or shipping requirements

Properties

  • · Form: Dispersion of graphene oxide sheets
  • · Particle Size: < 10μm
  • · Color: Yellow-brown
  • · Concentration: Upon request (pricing above based on 0.1 wt%)
  • · Monolayer content (measured @ 0.05 wt% in water): >95%*
  • · The Graphene Oxide weight content is guaranteed
  • · The dispersion volume is approximated
  • * At higher concentrations, the GO flakes tend to agglomerate and dilution followed by slight sonication is required in order to obtain a higher percentage of monolayer flakes.
