Dear all, ellipsometry is the most accurate technique in doing so. Thé first link is a thread discussing similar question. The second one is a comparative study investigating a comparison between different techniques. My Regards

A surface profiler is a quick way to measure the thickness of over 20nm. Otherwise you can use AFM to measure the thickness less than 20nm. You may need to find the area of nanocomposite coating and the area of no coating. The step height reflects the thickness of the films

Dear Ali,
You can try either cross-section SEM, AFM, or profilometer. If you use the Lambert-Beer app. to estimate your film thickness, the density of your composite can be simply estimated as the density (rho) of a mixture = mass of mixture/volume of mixture = (mA+mB)/V = (rhoA*VA + rhoB*Vb)/V
Hi Dear Ali Husnain
Preferably use the ellipsometry method. If this method is not available, you can cut the sample and determine its thickness using TEM and image J software. Also, AFM can be effective.
Dear Ali Husnain,
The technique or instrument to measure thickness always depends on the range. In our laboratory, we are using digital screw-gauge or micrometer to measure the thickness of polymer nanocomposite films (30-100 micron thick).
Thanks
