Abstract: | "We report on the discovery of an interesting dual colorimetric and conductometric response of synthesized water-based silver-decorated polypyrrole (Ag/PPy) nanowire to organic solvents, and the possible fabrication of a volatile organic compounds (VOCs) sensor based on the stimuli-responsive Ag/PPy nanocomposites. The dual-responsive nature of this material allows for a straightforward way to differentiate various VOCs within a broad polarity range by noncontact optical means via color transition, but also can provide highly accurate quantitative identification of each VOC by electronic detection" |
