二氧化硅微球的两种氨基化改性方法研究

Amino-modified Silica Microspheres

二氧化硅微球表面的官能化改性进一步拓展了硅球的研究与应用.实验中用两种方法对二氧化硅微球进行氨基化改性.通过茚三酮显色反应确定了氨基的引入;比表面积对比结果表明,两种氨基化改性方法对硅球的粒径大小影响不大.

The functionalized modification of the surface of silica microspheres expanded the research and application of silica materials.In this thesis,the silica microspheres with amide groups were modified by two different ways.The color reaction of ninhydrin certified the introduction of amino groups to the surface of silica microspheres.And the contradistinction of specific surface area of silica microspheres be-fore and after modification showed that both modified way did not influence the size of silica microspheres.
