For the thickness you can make a cross section and take SEM image.

Depending on the coating and the properties there are many adhesion tests:

Pull-off test

Tensile test

Bending test

Hardness test

Impact test

Stretching test

Please see ASTM

The easiest and most convincing way is to perform a confocal Raman Spectroscopy depth profiling of the sample in the (XZ direction). This should result in dinstict color coded images (a) the polymer and be (b) the glass substrate. This is because the different layers polymer/glass in the film can be clearly resolved and matched with their associated Raman Spectrum. One will therefore be able to estimate the thickness of each layer. You can also obtain using the same instrument ( Combined Confocal Raman Spectroscopy + AFM ) aperform AFM in the Digital Pulsed Force Mode in the non contact mode which should more information about such as (a) viscosity (b) adhesion (c) stiffness and etc.

The simplest qualitative determination of adhesion is cross-cut test ISO2409.

Hi, you can go for SEM, AFM or cross-cut test ISO2409.

Atomic Force microscopy is the best method to analyse the thickness of polymer in glass substrates

Hi, for sem cross-section analysis you can submerge a sample on liquid Nitrogen, the glass substrate will break and you will get nice cross-sections to analyse.

Other way to measure the thickness is by using a profilometer.

For the measure thickness and adhesion of a polymer deposited on a glass substrate, you can choose embedding method, and then using mirror polishing technique to get a proper sample for AFM or SEM.

Dear friends,

Thank you very much for your kind replies.

Hello dear, I am happy to contact you ..

Fish is calculated by method (Fizuo- Technique )

For measure the thickness of polymer coating can cut the sample longitudinal and test cross section by SEM and AFM
