溶胶-凝胶法制备纳米二氧化硅微球的研究
|
摘要
采用溶胶-凝胶法制备纳米二氧化硅,通过傅里叶红外光谱表征成分,用800倍数码显微镜观察表面形貌,探讨不同反应条件对纳米二氧化硅表面形貌的影响。纳米二氧化硅微球在不同溶剂中的分散性。结果表明,在酸、碱条件下,分别生成纳米二氧化硅溶胶和纳米二氧化硅微球;碱性条件下,反应温度和反应时间分别为40℃和4 h时,纳米二氧化硅微球呈现规整、均一的球型形貌;纳米SiO_2微球在有机溶剂中的分散性都较好,且分散均匀。
Nanometer silica was prepared by sol-gel and the product was characterized by Fourier transform infrared spectroscopy( FTIR). Meanwhile,the effects of different reaction conditions on the surface morphology of silica were investigated by 800 times digital microscope. Finally,the dispersibility of the nanometer silica under different solvents was discussed. The results showed that the gelatinous silica and silica microspheres are formed under acid and alkali conditions. Under alkaline conditions,when the reaction temperature and reaction time are 40 ℃ and 4 h,the obtained silica showed regular and uniform spherical morphology. The dispersion of SiO_2 nanoparticles in organic solvent is better,and the dispersion is uniform.
