Graphene Oxide (AIGO)

Properties of Graphene Oxide & Graphene are extremely different.

• Graphene Oxide does not absorb visible light & has low electric conductance, and shows higher chemical activity as compared to Graphene.
• Graphene Oxide particles are highly hydrophilic & form stable aqueous dispersions in wide range of concentrations.
• Graphene Oxide forms stable dispersions with organic solvents like ethylene glycol & dimethylformamide (DMF) & N-methyl-2-pyrollidone (NMP) & tetrahydrofuran (THF). This is attributed to the fact that hydrogen bonding takes place between the hydroxyl groups on the surface of Graphene oxide & solvent interface. This property enables films to be made on different substrates using simple drop-casting method followed by evaporating the solvent.
• Graphene Oxide films have high optical transparency.
• As hydroxyl and epoxy groups are present on the planes and carboxylic acid groups at the edges, allows Graphene Oxide to be chemically functionalized by different reagents.
• Non-covalent functionalization (by cation-π or van der Waals interaction) allows successful attachment of DNA or proteins to the surface of Graphene Oxide films which is useful for bio sensing applications.
