The invention relates to the use of at least one type of a polymer comprising a repetitive structural unit of formula (I), wherein X and Y = a simple link or a linear C¿1?-C¿50? group; R¿1? and R¿2? = H, CN, C(Z)¿3?, CH(Z)¿2?, CH¿2?Z with Z = halogens; NH¿2?, NHR¿3?, NR¿3?R¿4? with R¿3?, R¿4? = halogens, CH¿3? or a linear or branched, saturated or unsaturated C¿2?-C¿20? hydrocarbon chain, possibly comprising one or several heteroatoms and/or chemical functions containing at least one heteroatom; at least one R1 and R2 different from H; or a compound which comprises said polymer and one or several conductive charges and is used as a sensitive material in a sensor for detecting nitrate compounds. Said invention can be used for detecting explosive materials, controlling/monitoring air pollution and the quality of environment and for monitoring industrial sites.
L'invention concerne l'utilisation d'au moins un polymère comprenant un motif répétitif de formule (I) dans laquelle : X et Y = liaison simple ou groupe hydrocarboné linéaire en C1-C50 ; R1 et R2 = H, CN, C(Z)3, CH(Z)2, CH2Z avec Z = halogène ; NH2, NHR3, NR3R4 avec R3, R4 = halogène, CH3 ou chaîne hydrocarbonée en C2-C20 linéaire ou ramifiée, saturée ou insaturée, comprenant éventuellement un ou plusieurs hétéroatomes et/ou fonctions chimiques comportant au moins un hétéroatome ; au moins un de R1 et R2 étant de H ; ou d'un composite comprenant ce polymère et une ou plusieurs charges conductrices, en tant que matériau sensible dans un capteur pour détecter des composés nitrés. Applications détection d'explosifs, contrôle/surveillance de la pollution atmosphérique et de la qualité d'ambiances, surveillance de sites industriels.
