摘要
采用溶胶-凝胶法,以正硅酸乙酯为原料,不同浓度氨水溶液做催化剂制备了SiO2薄膜,用可见分光光度计,综合热分析仪、X射线粉末衍射等分析手段对薄膜进行表征。研究发现,随氨水浓度的提高,所制备的SiO2薄膜的透光率提高,薄膜与基底的附着力也相应提高。XRD分析结果表明二氧化硅薄膜具有非晶态的无序结构。
Silica films catalyzed by different concentrations of NH3-H2O were prepared with TEOS as main raw material by the sol-gel method.The samples were characterized by visible spectrophotometer,X-ray diffraction（XRD） and thermal analysis technology（TG-DTA）.Results showed that the light transmittance and adhesion of silica films were both increased with the increasing of the concentration of NH3-H2O catalyst.The structures of the silica films were non-crystal.
