摘要: 有机聚合物(或其活性单体)参与的硅醇盐的溶胶-凝胶(sol-gel)过程是达到聚合物与SiO2微观甚至纳米复合的一条良好途径[1,2].目前多以普通的硅醇盐为先驱物,它们在sol-gel过程中脱出的醇皆为低分子化合物,并且是非活性的,不能进一步形成聚合物,需加以去除,从而在制备过程中引起大的收缩(体积收缩达50%以上),导致材料包含大量气孔甚至发生开裂,且要求很长的制备周期(数周至数月)[3].

Abstract: Tetraacryloxyethoxysilane syntheslied by the reaction of 2-hydroxyethyl acrylatewith silicon tetrachloride was used in preparation of the transparent poly (2-hydroxyethylacrylate)/silicon dioxide composites by sol-gel method.The composition of the compositeswere analyzed by electronic energy spectroscopy, elemental analysis and thermogravimetry.The composites have transparency greater than 80%, with thermal stability being increasedwith the silicon dioxide content.

Key words: poly(hydroxyethyl arylate), silicon dioxide, composite, sol-gel method
