General description

Handling of large quantities of GO powder is not recommended since graphene oxide powder is thermally unstable. Graphene oxide paste can make storage and transportation of large quantities in a safe manner. Graphene oxide solutions of desired concentration or graphene oxide paper or sheet can be made from graphene oxide paste. Sonication is required to obtain single layers of graphene oxide. To make a concentrated aqueous dispersion that will not settle under gravity: add 25 mL water/1 g paste, stir overnight for 16 h, sonicate for 30 minutes in a mild bath sonicator. Centrifuge (effective diameter of the rotor is 23 cm) at 3500 rpm for 10 minutes to remove any large unexfoliated particles and decant the supernate to give ∼2 mg/mL graphene oxide in water. The above concentrate can be diluted and sonicated further to get single layer graphene oxide.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". High concentrated graphene oxide sheets provide the prerequisite viscosity to bind the electrode materials together and enable 3D printing. Using water as a green solvent makes this aqueous ink system feasible for processing and drying safety and low cost. Click here for more information.
