Influence of Nanostructuring Sensors Based on Graphene Oxide and PEDOT:PSS for Methanol Detection

Gas Sensor Based on Highly Effective Slot-Die Printed PEDOT:PSS@ZnO Hybrid Nanocomposite for Methanol Detection

“…8−12 In this context, organic conducting polymers including PEDOT:PSS have been successfully used in chemiresistive gas detection, especially for the detection of VOCs thanks to high molecular modification potentials and tunable properties. 13,14 Gas sensors utilizing a hybrid active layer that synergistically combines the properties of inorganic and organic materials led to high response and better selectivity at low temperatures due to mutually reinforced adsorption and electronic interactions. 15−18 Rashmi et al studied a nanocomposite of a conjugated copolymer composed of aniline and pyrrole and ZnO that showed good detection of methanol vapors at room temperature, fast response, and good recovery on exposure to gas vapor.…”

“…It has the advantages of biocompatibility, chemical stability, environmental compatibility, and low synthesis cost. − However, the biggest disadvantage of these sensors is their high working temperature, which limits their application in portable devices. On the other hand, organic materials can improve gas detection performance, as well as reduce the working temperature and improve its sensitivity. − In this context, organic conducting polymers including PEDOT:PSS have been successfully used in chemiresistive gas detection, especially for the detection of VOCs thanks to high molecular modification potentials and tunable properties. , …”
