Abstract: A new ionic liquid-polymer electrolyte was successfully tested in the planar amperometric solid-state sensor sensitive towards nitrogen dioxide. The electrolyte consists of 1-butyl-3-methylimidazolium hexafluorophosphate (BMIPF6) and poly(ethylene glycol) methyl ether methacrylate (PEGMEMA) in the ratio 57:43 mol. %. The analyte, gaseous nitrogen dioxide in air, was determined using the electrochemical reduction at900 mV vs. Pt/air on gold minigrid indicating electrode with Pt/air as a reference electrode. Dependency of sensor sensitivity on the indicating electrode area and relative humidity was determined. The sensor response is linear in the NO2 concentration range 0.3 1.1 ppm and is reproducible and long-term stable.
