Dear friend Seyed Hossein Hosseini Kakhk

One parameter that can be used to investigate the mechanical stability and structural strength of polymeric core-shell particles is the shell thickness. The thicker the shell, the more resistant the particles are to deformation and breakage during processing. Another parameter is the shell-to-core ratio, as a higher ratio can provide more protection to the core and improve the particle's mechanical stability.

In addition, techniques such as atomic force microscopy (AFM) and scanning electron microscopy (SEM) can be used to visualize the morphology of the particles and provide insight into their structural strength. The use of rheological measurements, such as storage and loss modulus, can also provide information on the deformation and viscoelastic properties of the particles.

Overall, a combination of these parameters and techniques can be used to assess the mechanical stability and structural strength of polymeric core-shell particles and predict their behavior during processing.

thank you dear Kaushik Shandilya for your answer

You can use AFM but only when equipped with a strain gauge. Note if there is no device for force measurement in AFM, only math model in another mode an probably another model is taken into consideration when someone talking about Force Measurement.
