high efficient 99% Graphene

Graphene is a new carbon material with two-dimensional structure. Graphene has excellent electrical, thermal and mechanical properties.The specific surface area of graphene prepared by our company is 500-1000m2/g and the thickness is 0.55-3.74 nm. Graphene has a very high specific surface area and is difficult to disperse in polar or non-polar solvents. At present, by adding dispersant in graphene solution, the graphene dispersion can be uniformly and stably dispersed by ultrasound.
