纳米金刚石是一种新型的碳纳米粒子,具有硬度高、化学稳定、良好的生物相容性和热传导性等优点,有广阔的应用前景。对于纳米金刚石的应用,大多需要对其进行表面修饰。本文主要结合近年来国内外研究成果,阐述了氢化、羧酸化、羟基化及其他表面修饰等纳米金刚石的表面修饰方法,总结了纳米金刚石在润滑、抛光、生物医学、复合材料等领域的应用。 Nanodiamond is a new type of carbon nano-particles, with the advantages of high hardness, chemical stability, good biocompatibility and thermal conductivity, and has broad application prospects. For the application of nano-diamond, most of them need to be surface-modified. In this paper, based on the research results at home and abroad in recent years, the methods of surface modification of nano-diamond such as hydrogenation, carboxylation, hydroxylation and other surface modification are described. The applications of nano-diamond in lubrication, polishing, biomedicine and composite materials are summarized.
