影响单壁碳纳米管氢气传感器的因素

Factors that influence the performance of hydrogen detectors based on single-wall carbon nanotubes

    摘要
  • 摘要: 单壁碳纳米管用于制造氢气传感器已有几十年的历史。由于单壁碳纳米管与氢气的相互作用很小，因此需采用了多种改性来辅助，改性物包括金属、金属氧化物与聚合物等。一些研究指出，当与碳纳米管上的官能团结合时，改性物可以使响应提高几个数量级。在目前的研究中，已开发了许多新的结构。此外，单壁碳纳米管的直径和手性等结构也会影响氢气探测器的性能。本文对单壁碳纳米管的改性进行了分类，并对其影响因素进行了讨论，旨在为制造高响应度和低检测限的探测器提供支撑。

     

    Abstract: Single-wall carbon nanotubes (SWCNTs) have been used to fabricate hydrogen gas (H2) detectors for several decades. It has been proven that they barely interact with H2 so that numerous modifications are used to assist this function. Additives include metals, metal oxides, polymers etc. Previous research suggests that the presence of functional groups on the SWCNTs may improve the response by several orders of magnitude. Recently, many different novel structures have been exploited, and structural parameters of the SWCNTs, such as diameter and chirality, also influence the performance of the detectors. Modifications of the SWCNTs are classified and other factors that influence the performance are also discussed, with the aim of accelerating the manufacture of detectors with a high responsivity and low limit of detection.
