Methacrylate hybrid materials (hybrimer) can be fabricated via UV cross-linking of methacryl-oligosiloxanes synthesized by simple sol-gel reaction of 3-(trimethoxysilylpropyl) methacrylate and diphenylsilanediol. Methacrylate hybrimer shows good curability, excellent optical properties, and reliable thermal/mechanical properties. However, formation of the organic network is, to some degree, inhibited by steric restriction of the bulky oligosiloxane cores, which would lead to the limited material properties of the hybrimer. To overcome this problem, in this study, various functional acrylic intermediates were introduced to the methacrylate hybrimer not only to enhance the cross-linking of methacryl-oligosiloxanes, and to tune the properties of the methacrylate hybrid material. As results, it is confirmed that the overall properties of the hybrimer were enhanced and tuned by incorporating functional acrylic intermediates in accordance with the result from hydrofluoric acid derived gel permeation chromatography (HF-GPC) analysis, which gives direct evidences for further cross-linkings or the curing behavior between the mathacryl oligosiloxanes. |
