| Research Abstract |
We have studied drying processes of polymer solutions on solid substrates, theoretically and experimentally, focusing on the mechanism of formation of the thin films, and prediction and control of the film shape. We have found a criterion on the formation of a thin gel-like layer on the surface of the solution, taking the elastic effect on the evaporation rate of the solvent into consideration. We have also found the initial condition dependencies of the shape of films and that the vapor distribution in air affects the shaping of deposit. We have proposed some methods for controlling shape of the film made by drying.
