Dynamics of the drying and the film formation process of a polymer droplets placed on a substrate.

Abstract

The dynamics of the drying process of a polymer solution droplet placed on a substrate is important in various modern technology, especially the ink-jet printing process. The process involves various challenging problems such as the transport of solvent and solute induced by solvent evaporation, the gelation and the contact line dynamics etc. We have been studying the phenomena the both experimentally and theoretically. In this talk, I will give an overview of our research.
