英文摘要：

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.
