摘要
石英晶体微天平(quartz crystal microbalance,QCM)是一种对质量变化敏感的器件,具有灵敏度高、成本低廉、操作简单、可实时在线检测等优点,在气体传感领域受到了广泛关注。敏感材料是石英晶体微天平气体传感器的关键组成部分,本文综述了不同敏感材料包括有机聚合物、超分子化合物、离子液体和分子液体以及近年来备受关注的纳米材料修饰的QCM对特定气体传感检测的研究现状,详细介绍了纳米材料为敏感膜的QCM气体传感器对不同气体传感检测的研究现状及相关敏感机理。最后,在国内外研究现状的基础上,展望了敏感材料的发展前景。QCM作为一种成本低廉、操作方便、测量精度高的气体传感检测器件,将会有更加广阔的应用前景。
Quartz crystal microbalance （QCM） is a mass-sensitive device, and has been attracting intensive attention in the field of gas sensor because of its many advantages such as high sensitivity, low cost, easy installation and inherent ability to monitor analytes in real time. Sensing material is a key issue for the range of application of QCM sensors. This paper reviews the current research status of sensing materials for specific gases, including polymers, supermolecules, ionic liquids, molecular liquids and nanomaterials. The current status and sensing mechanisms of QCM sensors using nanomaterials as sensing layer are introduced in detail. On the basis of the research status, a prospect is given of sensing materials. As a low-cost, easy operation, high- accuracy gas detection device, QCM would be more widely applied in the future.
