Dear Haider Umran, generally speaking the higher the MW, thicker is the film and vice-versa. This is because the spreading is difficult because of the viscosity. Other thing to consider that the high viscosity also hinder the ease of film drying. My Regards

Hi;

Generally the thickness of the films increases with the molecular chain of the polymers. Also the length of the chains plays an important role because the diffusion of the polymers is slowed down by the tangles of the chains.

With my best regards

Thanks a lot for the clarification.

My topic is focused on the relation between film thickness with the molecular chains and traps. Are there any references for that?

Thank you so much.

Are there any references can I use to get more information about that?
