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.
