Electrical Properties of the Gas Sensing Element NiO-PEDOT:PSS in a Model Gas Mixture with Nitrogen Dioxide
摘要
Abstract
A NiO-PEDOT:PSS composite has been developed as a gas-sensitive element of a conductometric sensor. The nature of the change in the resistance of this element in air has been studied. The electrical and sensory properties of NiO-PEDOT:PSS in a model gas mixture containing nitrogen dioxide (5–50 ppm) at room temperature were studied using impedance spectroscopy. Analysis of experimental data made it possible to determine the concentration dependence of the sensory response of NiO-PEDOT:PSS when exposed to nitrogen dioxide.
