RT Journal Article T1 New sensitive layers for surface acoustic wave gas sensors based on polymer and carbon nanotube composites A1 Sayago, I. A1 Fernández, M. J. A1 Fontecha, J. L. A1 Horrillo, M. C. A1 Vera, C. A1 Obieta, I. A1 Bustero, I. AB Surface acoustic wave (SAW) gas sensors based on polymers and carbon nanotube composites as sensitive layers were investigated for the detection of low concentrations of volatile organic compounds as octane and toluene. Several nanocomposites based on polyepichlorohydrin (PECH) and polyetherurethane (PEUT) with different percentage of multiwalled carbon nanotubes (MWCNT) were tested to study the effect of MWCNTs in the response of sensors. The sensors exhibited at room temperature high response to volatile gases (toluene and octane) but did not detect other gases tested as H2, NH3, NO2 and CO.
