摘要： 等离子体聚合物在结构上与普通的聚合物显著不同,它能形成含有活性基团的高度交联的网络结构,从而具有良好的均匀性及对基质的附着性[1,2].有关采用等离子体聚合膜的TSM传感器的报道不多[3,4].

Abstract: Anbutylamine plasma coated thicknessshearmode(TSM) acoustic wave sensor was prepared on the surface of quartz crystal using a plasma deposited technique. The response characteristics of the TSM sensor for a series of organic vapors were reported. It shows that the TSM can be used for sensing carboxylic acid vapor efficiently and possesses considerably long lifetime compared with the sensor coated by common chemical polymer. The sensor possessed good reproducibility, high stability and rapid response time to formic acid while coating with 96.40 g of plasmadeposited nbutylamine. Compared with acidbase titration method, the sensor can be .used for the determination of HCOOH sample with recovery rate of 96.6% to 104.2%.

Key words: n-Butylamine, Plasmadeposited film, Thickness-shear-mode acoustic wave sensor, Carboxylic acid vapor, Long lifetime for usage
