摘要
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 one of important nanostructure carbons and has attracted considerable attention in various fields owing to its outstanding hardness, high chemical stability, fine bioeompatibility and excellent thermal conductivity. Diamond nanoparticles are generally supplied as agglomerated powder because of their high surface free energy. It is necessary to be modified for most of its applications. On diamond surface some functional groups, e. g. , -COOH, -OH, -C-O-C can be created by detonation and oxidation purification at high temperature and high pressure. The dispersion of nanopartieles is another important issue. The progress in the surface modification of nanodiamond including hydrogenation, earboxylation, hydroxylation and other modification and the applications of nanodiamond in the fields of lubricant, polishing, biomedicine and composites were summarized in this paper.
