Abstract
Official abstract text for this publication.
A sensor for detecting phosgene includes a pair of electrodes separated by an electrode gap, and a layer of conducting polymer material positioned over and making electrical contact with the pair of electrodes, the layer of conducting polymer material being modified with an amine such that the electrical resistance of the conducting polymer material measured across the electrodes is responsive to changes in an amount of phosgene to which the conducting polymer material is exposed.
First claim
Opening claim text (preview).
What is claimed is: 1. A phosgene sensor, the sensor comprising: a pair of electrodes separated by an electrode gap; and a layer of conducting polymer material positioned over and making electrical contact with each of the pair of electrodes, the layer of conducting polymer material having been exposed to an aqueous solution of an amine to provide an amine modified conducting material such that the electrical resistance of the amine modified conducting polymer material when meas…
