What is the best method of depositing nanoparticles on a polymer substrate which is limited in temperature tolerance. How can the adhesion be improved?
Dear Abdolazim Hasseli, the following document gives a brief description of the different techniques. Surface topology, roughness, and preparation are essentials for good adhesion. Sometimes an extra surface modification/activation are also followed. If the system in question is given, may be further details are to be added. My Regards

Thank you. Actually my application is in polymer fiber optic core coating.
No thanks. I think there isn't a broad gap between the application in sensors and yours. Sure you will be inspired by that. Please check the following documents. My Regards

Dear Abdelkader BOUAZIZ
Can you suggest me the best way of removing the cladding of a polymer fiber optic and made it ready for new coating?
I don't have a practical experience in this field, just basing on my academic corses, bibliographic research term papers, and reading. Generally, chemical stripping is the most used as it is done in the free patent below. Others use mechanical stretching and other tips. My Regards

Colloidal nanoparticles (NPs) can be deposited uniformly on flat or rough and uneven substrate surfaces employing a standard centrifuge and common solvents. This method is suitable for depositing different types of nanoparticles on a variety of substrates including glass, silicon wafer, aluminum foil, copper sheet, polymer film, plastic, and paper, etc. The thickness of the films can be controlled by the amount of the colloidal nanoparticle solution used in the preparation. The method offers a fast and simple procedure compared to other currently known nanoparticle deposition techniques for studying the optical properties of nanoparticle films. https://link.springer.com/article/10.1007/s13204-014-0338-x
A large variate of techniques are available for nanoparticle deposition. Some relatively simple and fast methods include solvent evaporation, dip coating and spin coating. https://www.biolinscientific.com/blog/how-to-deposit-nanoparticles
