A modified dynamical model of drying process of a polymer solution having plural solvents coated on a flat substrate for a flat and homogeneous polymer film fabrication

摘要

We modify the former dynamical model of drying process of polymer solution coated on a flat substrate to dealwith drying process of solution having two kinds of solvents. As a result, we see that there is no essential difference between solute's distribution after drying in case of having two kinds of solvents and that in case of having only one kind of solvent and when there are over two kinds of solvents, solute's distribution after drying obeys the mean value of over two kinds of solvents' parameters, that is, it resembles one simulated numerically based on the mean value in case of having only one kind of solvent.
