Stanford Advanced Materials
Graphen flake usually have 1-8 layers and the average thickness is less than 1nm. Various dispersions of graphene nanoplates can be ordered instead of bulk powder, as making graphene dispersion.
Catalog No. GR0011
Specific surface area(m2/g) 200 ~ 1000
The single layer ration could be improved significatly and double layer graphene or triple layer graphene consist a large part amount the rest, if the graphene nanosheet is dispersed in solutions.
