Outline of Final Research Achievements |
A variety of end-functionalized polymer with both photo-reactive groups and amino groups was prepared. The resulting polymers were applied for an ionic bond formation of the amino-end-functional group with C8F17COOH in order to lead such amino groups to the top of polymer film surface by the surface concentration behavior of C8F17 group. Then, UV-irradiation allowed to photodimerize the photo-reactive group and to fix these functional groups at the film surface. Finally, C8F17 groups were quantitatively removed by a treatment with methanol, resulting in the amino-concentrated film surface formation. In the case that cinnamoyl group was used as a photo-reactive group, the surface enriched components were immobilized by photodimerization of cinnamoyl groups. Moreover, when coumarin group was used as a photo-reactive group, control of the mobility of film surface was achieved by reversible photodimerization of coumarin group at a different UV wavelength.
