Abstract(s) :

(Anglais) This paper presents a chemical sensor based on molecularly imprinted polypyrrole for acetaldehyde detection. This molecule belongs to the family of VOC’s and is known for its toxicity. The sensor working principle is the measurement of conductivity variations of polypyrrole films deposited on interdigitated electrodes. The molecularly imprinted polypyrrole (MIP) films deposited on the electrodes by direct electropolymerization in a bath containing pyrrole monomer, acetonitrile as solvent and acetaldehyde as template. Non imprinted polypyrrole (NIP) films are prepared in the same conditions without template. The behaviours of the films are compared by mass adsorption measurements with a quartz crystal microbalance and by impedance measurements. The MIP-based sensors show a rapid and reversible response to acetaldehyde in the ppm range while NIP give an insignificant signal.
