【摘要】 以正硅酸乙酯、钛酸丁酯、异丙醇铝和γ 缩水甘油醚氧丙基三甲氧基硅烷为先驱体,通过分步水解法制得SiO2 TiO2 Al2O3复合溶胶,利用提拉法在普通玻璃表面镀制无机 有机复合透明保护薄膜,通过各种测试方法,对SiO2 TiO2 Al2O3复合薄膜的结构和性质进行了分析,结果表明该薄膜具有致密、透明、耐磨擦等性能。由于铝、钛纳米氧化物颗粒的存在,使得硬度及耐磨擦性能比纯SiO2薄膜均有较大的提高。更多还原

【Abstract】 In this paper preparation and research of SiO₂-TiO₂-Al₂O₃ inorganic-organic composite films were investigated. Stable composite sol was prepared using tetraethyoxysliane, tetra-n-butyl titanate, aluminium isopropoxide and coupling agent etc by "order hydrolysis" of the metal alkoxides derived from sol-gel process. The films were prepared by dip-coating method. The different analysis showed that the nanocomposite films were dense, transparent and scratch-resistant. Properties like hardness and scratch-resistant are greatly improved in comparison with pure SiO₂ film.更多还原
