SENSORS AND METHODS FOR DETECTING ORGANIC CARBONYL SPECIES |
摘要 |
<p>A method for detecting an organic carbonyl species involves exposing a metal oxide-free film of a polyaniline to an environment suspected of containing an organic carbonyl species, detecting a change in electrical conductivity and/or an optical or luminescent property of the polyaniline, and, correlating the change in electrical conductivity and/or optical or luminescent property to a presence of the organic carbonyl species in the environment. Further, sensors for organic carbonyl species are disclosed having a metal oxide-free film of a polyaniline supported on an electrically insulating substrate. The method and sensors provide a good balance between response time and sensitivity, being considerably faster than metal oxide and metal oxide/polymer based sensors, while having greater sensitivity than other polymer-based sensors.</p> |
