factory high efficient 99% Graphene oxide powder with good price

Graphene oxide has a large number of oxygen-containing groups on its surface. It has good solvent solubility and affinity with polymers. Oxygen content of oxygen group is 30-40%, water solubility is very good, and the content of monolayer after dissolution is more than 99%. The size and thickness of the microchip ranged from 0.5 to 3 um and from 0.55 to 1.2 nm. No precipitation.

Graphene oxide powder is obtained by vacuum freeze-drying of graphene oxide sol. During freeze-drying, graphene oxide will not lose oxygen-containing groups on the surface and cause overlap between graphene oxide layers. The powder after drying is porous and spongy. It dissolves quickly and completely after adding water, and almost immediately restores the original sol properties.

The graphene oxide powder can be dispersed directly in aqueous solution and solvent (ultrasound is better) to obtain uniform and stable dispersion solution (see dispersion guide for specific dispersion method).
