Product Description

Single Layer Graphene Oxide 1-20um

We supply Single Layer Graphene Oxide 1-20um by the milligram, gram, or KG in powder form, dispersed, or as a coating on substrates. 

Our SLGO 1-20um (SLGO) uses no metal catalysts in it’s production, it is made by a modified Hummers method which is the oxidation of graphite using strong oxidizing agents to facilitate atomic layer separation. The Hummers method imparts significant functional groups onto the flake’s surface. It is well known that surface modification with oxygenated functionalities in sufficient quantities can make the material hydrophilic- meaning they can be dispersed in water without the use of surfactants.

Our graphene oxide is soluble in Di Water, NMP, DCB, or DMF so it can be easily dispersed into solvents for further processing without the use of surfactants. The average thickness of our single layer graphene oxide is 0.7-1.2nm as shown by the AFM image.  The conductivity & structure of graphene can be restored to our SLGO by reduction & annealing processes such as a hydrazine reduction or by annealing our graphene oxide at up to 400C in a forming gas (95% argon, 5% hydrogen) atmosphere.  Reduced graphene oxide is also available upon request.

We can provide single layer and few layer graphene oxide dispersions In Di Water, NMP, THF, or DMF. Hazmat shipping fees may apply. The standard concentration for dispersions is 2mgs/ml, up to 10mgs/ml is available.
