Investigation of a flexible, room-temperature fiber-shaped NH₃ sensor based on PANI-Au-SnO₂.

ABSTRACT: A sensitive compound was successfully obtained by coating polyaniline (PANI) on the surface of composite nanoparticles consisting of Au-loaded tin dioxide, named as PANI-Au-SnO₂, using an in situ polymerization method. NH₃ sensors in thin-film and fiber-shaped forms were prepared by inkjet printing and impregnation methods, respectively, based on PANI-Au-SnO₂. The response characteristics of these NH₃ sensors developed from composite sensitive materials were investigated in detail. Results indicate an effective response of the sensors to NH₃ at room temperature. The thin-film sensor demonstrated a good linear relationship between the resistance change and NH₃ concentration within the range of 5-40 ppm, indicating its
