  • Polyaniline nanofiber-amine composite materials for phosgene detection
    Patent number: 8961880
    Abstract: 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.
    Type: Grant
    Filed: July 14, 2008
    Date of Patent: February 24, 2015
    Assignees: The Aerospace Corporation, The Regents of the University of California
    Inventors: Shabnam Virji, Robert Kojima, Richard B. Kaner, Bruce H. Weiller
  • Polyaniline Nanofiber-Metal Salt Composite Materials for Arsine Detection
    Publication number: 20100005858
    Abstract: A sensor for detecting arsine 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 a metal salt such that the electrical resistance of the conducting polymer material measured across the electrodes is responsive to changes in an amount of arsine to which the conducting polymer material is exposed.
