I am working on the nanopatterning of carbon island deposited on ITO glass substrate and I want to measure the surface area of the glass that is covered by the carbon nanoparticle (number of particle per unit of area). The islands consist of sulfuric acid, sucrose and F127 (surfactant), is there any method I can use to determine the covered surface area? Thank you!
Yes Melody,
You can go for the cross sectional FESEM which clears how much is the coverage.
Or you can go with the DECTEK method.
And if you want to see the nano patterning of the carbon island which then create the improper coating or for the proper coating you can go for the AFM.
I think you could measure the active surface area/exposed area through gas chromatographic technique.
Hi Melody,
I think it is better if you use EPMA (Electron Probe Micro Analysis). It can show the coverage on some area, but it little bit difficult to measure the area.
You also can use AFM.
Hereby, I attach my publications that use EPMA analysis.
Hope it can help you. Good luck

Hi,
thank you for all your answers! May I ask how can you find the surface coverage using a cross sectional FESEM image, do you need a software afterwards to analyze the image to find the coverage?
