My goal is to use the spin coating technique to deposit a thin film of a material dispersed in an NMP-based solvent on a glass slide. As the solvent is very slippery, its adhesion is very poor over the slide and I am unable to deposit it. How can it be improved?
To enhance the adhesion of NMP-based films on glass slides during spin coating, consider surface treatments with silane coupling agents or adhesive coatings, and increase surface roughness through etching. Additionally, using plasma treatment and optimizing spin coating parameters can further improve adhesion properties.
Abdelhak Maghchiche sir thankyou so much for the response. May you reference some articles so that I can get an idea of the procedure.
Cleaning the substrate thoroughly... Like sonicating with acetone... Then etching with strong acids like HCl or even with aqua regia... Then washing several times with DI water
If possible plasma clean it... (Best way)
