Research Abstract

The condition that a skin phase appears at the free surface of polymer solution in the drying process has been clarified theoretically. A theoretical expression for the evaporation rate including the elastic effect due to gelation has been obtained. A simple model has been proposed which describes drying processes of polymer droplets on a solid substrate. This model enables a theoretical prediction concerning the shape of polymer film deposited after drying. Numerical simulations of multi-droplet systems have been performed. The results show the existence of interference effects among the droplets.
