Abstract
We have synthesized SiO2-main chain acrylate material successfully. First, the surface of SiO2 nanoparticle was modified with MPS (3-Methacryloxypropyl Trimethoxy Silane). Then TEGDA (Tetraethylene glycol diacrylate) was added to control the amount of organic-inorganic ratio(10-60wt%). The refractive index is between 1.4 and 1.6 and would be decreased with the increase of SiO2 amount. The optical transparency at 1310nm and 1550nm is above 95%. With 60wt% SiO2 amount, the thermal decomposition temperature will increase about 50℃. More than 40wt%, there is no obvious Tg below 200℃. The optimized sample is MPS/SiO2=0.25(wt ratio) and 40wt% SiO2.
