| Outline of Final Research Achievements |
In this work, effect of side groups on birefringence and its wavelength dispersion in cellulose ester films was investigated. It was found that the film processes, which were solution-cast and hot-stretching, affect the orientation of ester groups, leading that sign and wavelength dispersion of birefringence were drastically changed. Additionally, substitution degree and position of cellulose esters showed the strong effect on the optical property. Furthermore, addition of small molecules enhanced the birefringence in stretched films due to the cooperative orientation with the polymer chains. Anisotropic nano-pores generated form birefringence in cellulose triacetate film, resulting that the birefringence was successfully improved.
