纳米金刚石在水性介质中的分散研究

Surface Modification of Nanodiamond in Aqueous Medium

对纳米金刚石在水介质中的分散进行了探讨,并对表面改性过程进行了机理分析.利用机械力和化学力共同作用,对纳米金刚石表面进行改性,从而实现纳米金刚石在水介质中的分散和稳定;采用不同的处理工艺,使体系在酸性和碱性介质条件下均保持良好的分散.

The dispersion and stability of nanodiamond in aqueous medium are investigated. The combined effects of mechanical and chemical forces are conducted to modify the surface of nanodiamond particles aim to achieve the dispersion and stability of nanodiamond in water. When different chemical and mechanical processes are applied, excellent dispersion system of both acidic and alkaline aqueous medium can be obtained. Surface modification mechanism of nanodiamond is also discussed.
