通过将硫/碳纳米管混合物暴露在Ar/H气态等离子体中，发展了一种单壁碳纳米管硫代化的方法。X射线光电子能谱证明了碳纳米管样品中碳原子上硫的存在，拉曼光谱结果表明，处理后的碳纳米管结构保持不变。报道的方法的另一个优点是纳米管上不存在多余的氧。硫代化的碳纳米管可以自组装到金电极上。我们的硫代化碳纳米管的方法为制备基于碳纳米管的纳米电子电路的功能化管提供了一种可靠和简单的方法。
A method for the thiolation of single-wall carbon nanotubes has been developed by exposing a sulfur/carbon nanotubes mixture to an argon/hydrogen gaseous plasma. X-ray photoelectron spectroscopy provides evidence of the existence of sulfur attached to carbon on the carbon nanotubes samples and Raman spectroscopy results show that the carbon nanotubes’ structure has been preserved after the treatment. One added advantage of the reported method is that excess oxygen is not present on the nanotubes. The thiolated carbon nanotubes are shown to self-assemble onto gold electrodes. Our method for thiolating carbon nanotubes provides a reliable and simple way for preparing functionalized tubes for nanoelectronic circuits based on carbon nanotubes.
