Graphene oxide

A large number of oxide-containing group surface, having a good solvent solubility and the affinity of the polymer. Oxygen content of oxygen-containing groups is 30 to 40%, very good water-soluble, single content is more than 99% after the dissolution. Microchip size 0.5 ~ 3μm, the thickness is about 0.55 ~ 1.2nm. No precipitation. Graphene oxide powder is obtained by drying graphene oxide sol by vacuum freeze. Graphene oxide in a freeze-drying process is not lost due to the
