| Outline of Final Research Achievements |
In this project, SiOC membranes were fabricated by utilizing triethoxysilane (TRIES) and vinyltrimethoxysilane (VTMS) via sol-gel method. Amorphous SiOC structures were designed via the Si-O-Si unit by hydrolysis and condensation of silsesquioxane and the Si-C-C-Si unit via in-situ hydrosilylation. The network pore size was successfully controlled by the precursor ratio and thermal and oxidative stability was higher than conventional organosilica membranes.
