Abstract
A device for detection of a BTEX component in a liquid or gaseous phase including a sensor for producing a signal representative of the detection of the BTEX component. The sensor includes a layer of a material intended to be in physical contact with the phase, the material comprising a polymer having substituted benzyl group which is repeated more than ten times. The benzyl group comprising fluorine atoms and, at most, two other components selected among hydrogen, halogen atoms, and C1 to C2 alkyl groups.
Claims15
A device for detection of a BTEX component in a liquid or gaseous phase comprising a sensor adapted for producing a signal representative of the detection, the sensor comprising at least one layer of a material sensitive to the BTEX component and intended to be in physical contact with the phase, the material comprising a polymer including a sequence of the following formula (I):
- wherein:
- R-Bz is a unit repeated n times,
- n is an integer greater than 10,
- R is an organic group, and
- Bz is an at least partly substituted benzyl group of the following formula (Bz):
- wherein:
- at least three independently selected ones among Z1, Z2, Z3, Z4 and Z5 are fluorine atoms, and
- the at most two others among Z1, Z2, Z3, Z4 and Z5 are selected among hydrogen, halogen atoms, and C1 to C2 alkyl groups.
