abstract |
The invention relates to the use of at least one polymer comprising a repeating motive of formula (I) in which: X and Y = single bond or C1-C50 linear hydrocarbon group; R1 and R2 = H, CN, C (Z) 3, CH (Z) 2, CH2Z with Z = halogen; NH 2, NHR 3, NR 3 R 4 with R 3, R 4 = halogen, CH 3 or linear or branched, saturated or unsaturated C 2 -C 20 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 H; or a composite comprising this polymer and one or more conductive fillers, as a sensitive material in a sensor for detecting nitro compounds. Explosive detection applications, control / monitoring of atmospheric pollution and ambient quality, monitoring of industrial sites. |
