How to calculate the number of nanosheets in a fixed volume of aqueous colloidal solution with known concentration. Any research paper suggestion?
Hi,
I think you are talking about graphene, HR-TEM is the best way to find a layer thickness (from d space) or number of layers.
1. Use TEM to estimate the NS dimensions
2. Estimate/find the density of the material to give you mass per nanosheet.
3. Provided that the solution is pure (only nanosheets and water), dry a known volume of the dispersion extensively and weight.
4. Divide the total mass by the mass of a single nanosheet.
NB. If there is a organic capping agent, you will need to use TGA to estimate the mass fraction of this component.
Thanks a lot @ Dr. Adam Perriman
