Abstract
Thin films of polyamide 6 (with various concentrations) were deposited by spin-coating method (at various rotation speeds) and surface morphology of these films was analyzed by scanning electron microscopy. Following this analysis it was revealed that deposited film thickness depends on solution density, its viscosity, rotation speed and rotation time. In the context of multi-scale type theories, a theoretical model which explains our experimental results is established. Keywords: spin-coating, polyamide, thin film, multi-scale theory
