摘要：

The results from the first large-scale simulation of solvent evaporation from a solvent-polymer solution were analyzed. It was observed that the polymer density gradient were formed at the film/vapor interface. The rate of the solvent evaporation from the film was found to depend strongly on the magnitude of the density gradient. The magnitude of the density gradient depended on the time and also on solvent concentration in the system.
