| abstract |
The invention relates to the use of at least one polymer comprising a repeating unit of formula (I): in which: X and Y = single bond or linear C1-C50 hydrocarbon group; R1 and R2 = H, CN, C (Z) 3, CH (Z) 2, CH2Z with Z = halogen; NH2, NHR3, NR3R4 with R3, R4 = halogen, CH3 or linear or branched, saturated or unsaturated C2-C20 hydrocarbon chain, optionally comprising one or more heteroatoms and / or chemical functions comprising at least one heteroatom; at least one of R1 and R2 being ≠ of H; or of a composite comprising this polymer and one or more conductive fillers, as a sensitive material in a sensor for detecting nitro compounds.Applications: explosives detection, monitoring / monitoring of atmospheric pollution and the quality of atmospheres, monitoring of industrial sites. |
