【摘要】 目的在透明玻璃基板上通过直接火焰气溶胶沉积和原位退火快速合成水稳定性、透明防雾SiO2,TiO2,SiO2-TiO2涂层。方法联合使用火焰喷雾热分解反应器与基片支架合成和涂层沉积TiO2,SiO2-TiO2和SiO2纳米结构于7.5 cm×2.5 cm的玻璃基板上。结果在无预处理的情况下在玻璃基板用包含硅前体的HMDSO或TEOS等FSP溶液制备了直径为10~15 nm和长度为数十至数百纳米长的SiO2纳米纤维或纳米线。结论该制备工艺可行性好,质量控制方法简便、可靠。更多还原

【Abstract】 【Objectives】Study and try to achieve a method of rapidsynthesis of water stable, transparent anti-fogging coatings of SiO2, TiO2, and SiO2-TiO2by direct flame aerosol deposition and in situ annealing on transparent glass substrates. 【Methods】AFSP reactor was used in combination with a substrate holder as described in detail elsewhere for synthesis and direct deposition of TiO2, SiO2-TiO2, and SiO2nanostructured coatings onto glass substrates of 7.5 cm 2.5 cm. 【Results】SiO2nano-fibers or nano-wires 10~15 nm in diameter and tens to hundreds of nanometers in length were made by FSP of solutions containing silicon precursors such as HMDSO and TEOS on glass substrates without any pretreatment. 【Conclusion】The preparation technology is feasible, and the quality controlling method is simple and reliable.更多还原
