利用强氧化性酸和真空热处理对尺寸为50 nm 的金刚石微粉进行表面改性处理并进行研究。通过 XRD 、Raman 、TG‐DTA 以及 FTIR 等分析手段测试了纳米金刚石的表面结构和耐热性能。研究结果表明：这一工艺可以去除纳米金刚石表面大部分吸附杂质，提高耐热性能，但羟基和羰基等基团难以去除。

The surface of nano‐diamond particles ( 50 nm) was modified by strong acid , and pretreated by heat treatment in vacuum . The nano‐diamond surface structure was characterized by X‐ray diffraction ( XRD ) , Raman spectroscopy and Fourier transform infrared spectroscopy ( FTIR ) . The thermogravimetric‐differential thermal analysis( TG‐DTA) was used to investigate the heat resistance of nano‐diamond . The results showed that this method could remove most impurities on the surface of nano‐diamond and raise the heat resistance of nano‐diamond . But some groups were difficult to remove , such as the hydroxyl and carbonyl groups .
