通过使用元素硫的光解开发了一种用含硫官能团改性金刚石粉末表面的有用方法。通过 XPS、DRIFT 和质谱分析证实了金刚石表面引入了含硫官能团。硫改性金刚石粉末通过含硫键表现出对金表面的表面附着行为。简而言之，将改性金刚石粉末暴露于金胶体中导致金纳米颗粒附着在金刚石粉末上。在硅基底上用金薄膜处理改性金刚石粉末，可以通过自组装通过硫键使表面附着的金刚石粉末对齐。
A useful method of modifying the surface of diamond powders with sulfur-containing functionalities was developed by the use of the photolysis of elemental sulfur. The introduction of sulfur-containing functional groups on the diamond surfaces was confirmed by means of XPS, DRIFT and mass spectroscopy analyses. The sulfur-modified diamond powders exhibited surface-attachment behavior to gold surfaces through the sulfur-containing linkage. In brief, exposure of the modified diamond powders to gold colloids resulted in gold nanoparticles being attached to the diamond powders. Treatment of the modified diamond powders with gold thin film on Si substrate afforded alignment of surface-attached diamond powders through sulfur linkages by self-assembly.
