A high-performance flexible gas sensor based on self-assembled PANI-CeO2 nanocomposite thin film for trace-level NH3 detection at room temperature

Advances in designs and mechanisms of semiconducting metal oxide nanostructures for high-precision gas sensors operated at room temperature

“…The morphology and sensing performance of flexible RT NH 3 gas sensors based on PANI-CeO 2 nanocomposite thin films are stable after being bent/cycled for 500 times. 415 Furthermore, adding noble metals into the SMON/PANI composites can further improve their RT sensing performance. For example, after adding Au nanoparticles, the response of the RT NH 3 gas sensor made of the composite of mesoporous In 2 O 3 nanospheres/polyaniline has been increased up to 4 times higher.…”

Flexible Sensors—From Materials to Applications

“…There are a few reports on the functionalisation of conductive polymers to improve their sensing performance. Polyaniline (PANI) was functionalised to selectively detect various gases [514,515]. Functionalisation of PANI was applied to flexible sensors with the introduction of CeO 2 doped PANI [515], which improved the sensitivity 180% and the time response by 600 s to detect 30 ppm of NH 3 .…”

Investigation of the structural, optical and gas sensing properties of PANI coated Cu–ZnS microsphere composite

“…This could be due to the presence of p-type PANI and n-type Cu-ZnS, which gives a superior carrier transport path in the PANI/Cu-ZnS composite sensor. 53…”
