| Abstract: | In this paper, we take MMA, TEOS and KH-570 as the primer materials to manufacture low shrinkage, high light performance bulky PMMA/SiO2 hybrid material through sol-gel method successfully. The micro-structure and a few performances of the acquired PMMA/SiO2 hybrid materials are characterized with TEM and TG. The volume shrinkage and reaction mechanism are also analyzed. |
