General description

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.

Application

GO may be used to deliver a controlled dosage of bone morphogenetic protein-2 for bone regeneration. It may be used to fabricate graphene-based transparent conductive electrodes. GO is attractive for use in electronic devices. In addition to being the components in electronic devices, GO and rGO have been used in nanocomposite materials, polymer composite materials, energy storage, biomedical applications, catalysis and as surfactants.

Storage and Stability

Seal well, prevent from light and store it in a cool room.
