纳米金刚石是一种较新的纳米材料，具有广阔的应用前景。本文采用X射线衍射（XRD）、能谱（EDS）、高分辨透射电子显微镜（HRTEM）、傅里叶变换红外光谱（FTIR）、拉曼光谱（拉曼）和差示扫描量热仪（DSC）等方法对爆轰合成的纳米金刚石的结构和表面状态进行了全面的分析。结果表明，纳米金刚石颗粒呈球形或椭圆形。平均晶粒尺寸约为5 nm。纳米金刚石表面含有羟基、羰基、羧基、醚基树脂等官能团。纳米金刚石在空气中的初始氧化温度约为550 ℃，低于块状金刚石。
Nanodiamond is a relatively new nanomaterial with broad prospects for application. In this paper, a variety of methods were used to analyze comprehensively the structures and the surface states of the nanodiamond synthesized by detonation, for example, X-ray diffraction (XRD) spectroscopy, energy diffraction spectroscopy (EDS), high resolution transmission electron microscopy (HRTEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy (Raman) and differential scanning calorimeter (DSC). The results show that, the nanodiamond particles are spherical or elliptical in shape. The average grain size is approximately 5 nm. The surfaces of the nanodiamond contain hydroxy, carbonyl, carboxyl, ether-based resin, and other functional groups. The initial oxidation temperature of the nanodiamond in the air is about 550 °C, which is lower than that of the bulk diamond.
