| Outline of Final Research Achievements |
We have prepared nano-structured and porous polymer materials using photo-chemical reactions. The nanostructures were formed on the surface of a composite film of photo-crosslinkable silsesquioxane (SQ) and phenolic resin with additives such as photo-radical initiator and a photo-base generator after UV irradiation and alkali treatment. The experiments with different UV irradiances and temperatures revealed that the photo-reactivity of SQ strongly affects the morphology of the nanostructures. Furthermore, the effect of chemical structure of the SQ on the photo-reactivity and surface hardness was also evaluated, and SQ species with both high photo-reactivity and high surface hardness were explored.
