Paper Abstract

Drying process of polymer solution coated on a flat substrate is very important in various industrial applications. Then we have proposed and modified a model of drying process of polymer solution coated on a flat substrate for flat polymer film fabrication. In the previous study, we added Marangoni effect as pseudo-negative diffusion on an upper gas-liquid interface to the former model. And we saw through numerical simulation of the modified model that solute on upper gas-liquid interface was attracted more strongly to the edge due to Marangoni effect. In this study, we show that this effect is remarkable on upper gas-liquid interface, while the effect extends to sufficiently inside of the polymer solution film.
