Single Layer Graphene Oxide, >50µm, >98%

Graphene oxide powder is obtained by freeze-drying graphene oxide sol under vacuum. During freeze-drying, graphene oxide does not lose its surface oxygen-containing groups or experience interlayer overlap due to heating. The dried powder is loose and porous, resembling a sponge. After adding water, it can be ultrasonically broken up for 30 minutes to restore its original sol properties, resulting in a uniform and stable dispersion.
