| 摘 要： | 探讨了纳米金刚石在水介质中稳定分散的问题, 利用粒度检测、光电子能谱、表面电性分析和红外光谱分析等手段, 对表面活性剂的组合使用在纳米金刚石表面改性中的作用机理进行了讨论。研究发现, 加入单一的表面活性剂往往不能使纳米金刚石在介质中稳定分散, 而组合使用离子型表面活性剂和非离子型表面活性剂, 可以对纳米金刚石进行表面化学修饰改性, 从而得到稳定分散的体系。

| Abstract: | The stable dispersion of nanodiamond in aqueous medium is investigated. The action mechanism of combined use of surfactants on modification of nanodiamond surface is also analysed using such analysis methods as size measurement, X ray photoelectron energy spectrometry, surface potential measurement and infrared spectrometry. It is found that stable dispersion of nanodiamond in aqueous medium can not be achieued by separate use of surfactants, and combined use of ionic and non ionic surfactants can lead to surface chemical modification of nanodiamond, establishing a stable dispersion system. |

| Keywords: | nanodiamond dispersion surfactant combined use surface modification |
