中文摘要:
      采用微波等离子CVD方法在QCM传感器电极的表面沉积了一层超疏水性纳米膜(聚TMMOS有机硅氧烷),研究了其检测有机物的选择性和灵敏度。结果表明:改性的QCM电极表面选择性吸附有机物,而抑制了水分子的吸附;制得的超疏水性纳米膜的比表面积较大,使得有机物吸附量较大,提高了检测有机分子的灵敏度。该传感器能够应用于高湿度环境下有害有机物的检测。
英文摘要:
      The hydrophobic nano-film(trimethylmethoxysilane) was prepared on quartz crystal microbalance (QCM)sensors by means of microwave plasma chemical vapor deposition. The choice performance and sensibilisty for test organic substance were studied. The results show that: modified QCM electrode surface selectively adsorbs organic compounds to inhibit the absorption of water molecules. By controlling the film forming conditions, increased the film surface area to increase the organic matter adsorption to enhance the sensitivity of detection for organic molecules. The sensor can be used to detect of harmful organisms in high-humidity environment.
