Organic–inorganic hybrid material was synthesized by double polymerization processes i.e. a sol–gel process and organic polymerization respectively. For this study, hybrid monomer, 4-vinyl ether-phenyltriethoxysilane (VEPTES) was used as starting building block. First, the silica matrix with tunable ratio of siloxane and silanol units was synthesized by a sol–gel process under acidic conditions and
有机-无机杂化材料是通过双重聚合过程合成的,即溶胶-凝胶过程和有机聚合过程。在本研究中,杂化单体4-乙烯基醚-苯基三乙氧基硅烷(VEPTES)被用作起始构件。首先,在酸性条件下通过溶胶-凝胶法合成具有可调的硅氧烷和硅烷醇单元比例的二氧化硅基质,并通过乙烯基醚基的阳离子光聚合形成有机网络。矿物和有机聚合动力学分别由液体29监测Si-NMR和IR光谱。研究并阐明了硅酸盐骨架对有机光聚合过程的影响。已经使用近红外光谱法研究了这种新型杂化材料的光学性能。
