Presentation Summary

  • Conducting polymers as sensors in the form of an array for measurement of complex mixtures of volatile chemicals
  • When exposed to analyte vapours, the electrical conductivity of the polymer film changes. This is correlated quantitatively to the concentration of the vapours, and is readily reversible.
  • Methods of deposition of conducting polymers onto polyimide substrates
