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.6enginfo:eu-repo/semantics/restrictedAccessjournal article10.1016/j.snb.2011.12.031Carbon nanotubesCompositePECHPEUTSAW gas sensorsVOCsElectronic, Optical and Magnetic MaterialsInstrumentationCondensed Matter PhysicsSurfaces, Coatings and FilmsMetals and AlloysElectrical and Electronic EngineeringMaterials Chemistryhttp://www.scopus.com/inward/record.url?scp=84870236104&partnerID=8YFLogxK
