In this paper, PLF, LSFA and DKAP, three linear hydrogen-bond acidic (HBA) polymers synthesized in our laboratory and one commercial available hyperbranched HBA polymer HC were coated on 434 MHz surface acoustic wave (SAW) devices for rapid detection of volatile organic sulfur compounds (VOSCs). Sensitivity and selectivity of the polymer-coated sensors were studied by exposing to VOSCs in the concentration...
Three polymers were chosen for a surface acoustic wave (SAW) sensor array and a pattern recognition approach. Based on a data set collected from 10 candidate sensitive materials for 12 analytes, the selection was accomplished by principal component analysis (PCA) and cluster analysis(CA) methods. Then, the chosen polymers were deposited on three SAW devices combined into an array, and PCA was adapted...
