| Outline of Final Research Achievements |
Regarding the spherulite growth from high viscosity solution film, we focused on crystal growth from aqueous ascorbic acid solution as the main experimental system. In order to quantitatively characterize the fluidity of the solution film solution in a metastable state during crystal growth, flow analysis was performed and change in film thickness was measured. Based on measurement results we obtained, we proposed a simple mathematical model for spherulite growth by considering the fluidity of the solution, which seems to be applicable to other spherulite growth systems from high viscous thin solution film.
